My own opinion on PvE mode.
Hi, i just wanted state a list about odyssey: extraction and a real bit of invasion. The mode itself I think that a PvE mode is Always good for push out the stress of playing with or against toxic player of the usual game. Both of the mode look fun and really challenging even with the onslaugh difficult. The reward was nice for both of the event and the satisfying on beat the boss was really high. Playing powerful hated champion here look more fun and interesting (mostly because it kill the part of play against it eg Miss fortune or yasuo). Adding more level of difficult on odyssey: extraction was a great move forward from invasion mode even tho it was really cool without that. Btw here is my tough.
Augment I think with the 90% of odyssey: extraction player i can agree that this is the most fun of this mode. Fell your power increased by different way (you can play different augment and still working) but i think that the best part of the augment is that you have to unlock them (basically your power start from 0 to get all of them) making you play the game more and more and more. Even tho some of them are not "Visual" they still look good and fun. A small QoL that i would like to get is the fact that i'm able to know the other ally augments before to start the game (at least the number) There is just a few augment that look too much weak or unsatisfying for example :
Jinx
Barrage -> This is basically a stronger runnan on rocket, hovewer it has a small problem and that's that require Q stack. Even tho building up stack it's not that hard, i fell like it's a bit frustatying to build up damage with minigun and then switch to rocket one. If i picked up Barrage I end up always picking Plan A mostly because it give me a free Q stack and look less cluncky than build with q. I think that Whalebones should give stack with Q so jinx can use Always her Q instead of basic auto for greating clear (it would still be a weak version but a sustained one of Comet and Arsenal).
Plan Z -> This just need a different tooltip (instead of 25 for each armor/mr/health item, it should be X ad for each Y armor,Z mr, W health).
Hoppers and Bamboozle -> Even tho i know that scorcher is in a good way, i think that this aug are a bit akward to play without other : Hopper basically return CDr for each E that damage the enemy but with only 3 it's just weak and Bamboozle basically turn E into a 9 granade instead of 3 with increased dmg. I think that the effect of this aug should be swap (Cdr ref to bamboozle and dmg increased to hopper).
Ziggs and sona
I think that ziggs is fine by me and same goes with sona.
Maybe seekers could be rewritten that if you took hexhealing it would automatically searching for ally instead of enemy only.
Sona could just use a improved range of W heal while using Benediction since sometime it would still heal only 1 player because they are not real close.
I don't get the real point of harsh (maybe 
sinergy? or yasuo W windwall with crit?).
Yasuo
Silvered -> I dislike this one. i think Silvered should be turned into both of the ways : for each x ap you gain 1% increase physical damage or for each 2 ad you gain 1% increase magic damage.
Actually there is no real "AP aug" for yasuo except for this flicker (since it apply effect on hit so 
are viable).
Malphite
I don't find malphite aug weak but i would like too see real tank aug. Malphite aug are distribuite across : -Ap aug -AD aug -Bruiser aug -"utility aug" (R augment and E armor and mr red) There is nothing that increase malphite tankiness.
Mission
This is the hardest part of my list. Mission look a bit too hard but i'm fine with that. Sometime mission end to be like a "normal gameplay" with a bad reward. This time finally we got a really HIGH reward because the mission was really challenging so i'm really fine with the difficult of this one. What most of us notice it's that they reward ONLY the 5 man player (at least the best mission). There is nothing for the individual player and the troll/afk are basically ruining the mode (which i think i'm agree with that because they are playing different mission). I still think that the game need a 5 player mission (Create coordination, friendship and cool teamcomp) but otherwise i think that the Solo player should be able to do their mission without forcing other to play their own game. Invasion was a trouble because it turn player to play "without support" if i remember so it force all the player to don't pick support champs which was annoying. This trouble has been keeped into odyssey: invasion without fix the real issuo (the solo player). I think the mission should work like this:
Augment line :
The power of 5. Play Odissey: onslaugh with 5 friend with only 2 augments 0/1
or Always fear the Death. Play Odissey: onslaugh with only 2 augment without dying more than 2 (+1 life for each 2 less augments from your team max 8) 0/2
Why i'm doing this? Well i just wanted that since having 5 friend playing with 2 aug it's good and should be faster than the other one since they are ALL forced to play with 2 aug. The fact that they should be premade would prevent the unfun fact of being forced to playing what other of your teammates want. I thinked about that solo player should be forced to play the 2 aug (basically it still be a challenge) but with a harder difficult mostly because other ally could still use 6 aug so the game would be too easy to do instead of 5 man aug. So i turned to a Death count (which mean that if you play with 4 player with 6 aug, you have to play very but very safe but if you play with 4 player with 4 aug you have 6 life instead of two) I'm not sure if the player should be able to do the first mission without friend mostly because i think that it would still create toxic situation since most people would like to do other mission before do the challenge one.
5 man champs Damn this is the best cool line since you are allowed to play with more augments but i think it's still debatable on Solo since it require 5 man. I thnk this one should be put in this perspective: Eg: AoE is better. Play 5 ziggs or sona with 5 friends 0/1 or There is Always time for healing Play ziggs with "Hexhealing","refresher",Leftovers" 0/1 and Play sona with "Benedictions","oasis","flurry". 0/1
I think that forcing player into a 'Playstile' is the best way to go, you can still choose 2 aug but picking up the "Mission" upgrade look more fun tough.
Monster and Obstacle Monster are a lot interactive and fun before onslaugh, but when it come onslaugh, they turn be to play the same thing "Dealing absurd level of damage" which turn them to be more hp and cc i have, more strong i am leaving no difference between the utility on "Eg HOGTONGUE which pull you to him" and the only damage one. SQUIDTOOTH and CRIMSON STINGER -> They look too powerful, The laser of Squidtooth it's too fast for how much damage it does and Crimson Stinger is basically a Death sentence since it grab into a storm,volcano or laserbeam. I would expect SquidTooth damage lower since it's an AoE effect and crimston stringer suppression reduce by at least 0,5 s (it last too long). ARCRAPTOR and SKITTERBEAK -> i'm fine with them, just ARCRAPTOR is a bit too fast but otherwise it's ok. SHIMMERSTRIKER-> too weak, i barely notice him. ANCHORTAIL-> i think this moster is a bit counterintuitive since you have to walk in to dodje it, (maybe a clear effect that's it's a safe area like a green one?) DOZERMAW and HOGTONGUE -> i hate both of em, They deal massive damage, be a lot tanky and has a CC (Hogtongue it's hard to deal on short range).
Future of PvE
Before to see a third version of "PVE mode", i would like to see a "reevaluated" version of invasion with augments and mission that reward both of individual player and party player. I would be really happy to see more champs with aug (expecially syndra since her ult it's basically a joke on invasion). I would also expect sona to join the starguardian line since she has already 15 augment and implementing her in the starguardian mode should be easy (jinx is alredy in here). After implemented the star guardian line (with augments), some of them could be bringed on odyssey (Eg Janna and missfortune since they look like they has the "leader" personality). It would be a lot fun if they do after that a "Bad" version of the mode (instead of hero, you would play the villan) for example dark star line?
