Ok so I am a Poppy one trick and I will give you my opinion,
Movement speed reduced from 345 to 335.
Attack damage increased from 64 to 67
Mana reduced from 280 to 240.
Armor reduced from 38 to 35.
Health increased from 540 to 600.
Health per level scaling increased from +90 to +120.
Attack range increased from 125 to 135.
I don't like reducing the movement speed, we need it to land our e stun.
We don't need more attack damage this is mostly useless for us.
Poppy has one of the lowest mana pools in the game, lowering that would make early game difficult which 
should be best in.
You haven't mentioned the passive part of Steadfast Presence, if it is staying the same, I don't really like the decrease in armour.
More health level 1 is nice, but not needed.
More health scaling is very overpowered, we can easily hit 3800+ without this increase you mention.
We use our q for short range poke, and our passive for longer range poke, I don't see why her attack range should be changed and I see no immediate benefit for +10 attack range.
Iron ambassador magic damage bonus REMOVED.
Iron ambassador now grants 30/40/50% bonus attack speed for 4 seconds when picked up.
Iron ambassador now grants 5/10/15% bonus movement speed for 1 second when picked up.
You might this you buffed the passive with your changes, but I do not agree here, this magic damage is very important for securing kills (20 magic damage lvl1) and we depend on that magic damage to kill enemy top laners who are tanky. I see little benefit for bonus attack speed, we use 
so we auto q auto then run away as q is 90% of our damage so more as isn't helpful. The movement speed could be too strong, perhaps if it was active while moving towards the buckler it would make sense, however I believe the passive is strong already and has good scaling.
"Hammershock base damage from 40 to 120 REMOVED.
Hammershock scaling from 80% of bonus AD REMOVED.
Hammershock percentage of target's maximum health changed from 8% physical damage to 5% true damage.
Hammershock scales 100% of total AD in physical damage and 80% of total AP in magic damage.
Hammershock now has (2) charges. A new charge every 10/9/8/7/6 seconds.
Hammershock range increased from 430 to 510.
Hammershock enhances your next auto-attack with 1.5 seconds of Grievous Wounds."
All this is absolutely ridiculous, our q is incredibly strong already, removing the 80% does nothing for us unless you are troll building. Imo our q is our most broken ability.
Steadfast Presence mana cost changed from 50 to 40/60/80/100/120.
Steadfast Presence range increased from 400 to 450.
Steadfast Presence cooldown decreased from 24/22/20/18/16 to 18/17/16/15/14 seconds.
Steadfast Presence bonus movement speed increased from 32/34/36/38/40% to 50/55/60/65/70%.
Steadfast Presence length of time reduced from 2.5 seconds to 1/1.25/1.5/1.75/2 seconds.
Steadfast Presence now causes a 20% slow for 1 second to any targets affected.
You already reduced our maximum mana, which I think at that point would make her have the smallest mana pool in the game (or one of the smallest)
We don't need more range, the duration is very small already you need skill and practice to use it effectively, considering the fact it only blocks one champions dash and now would only last 1 sec level 1 (we max this last 70% of the time) it would be too difficult to protect our team. More bonus movement speed lol we don't need it. A 20% slow for one second? they get stunned for about one second already if they dash into it (might be half a second not really sure) so I that may be a waste of code anyway you might want to check that.
Heroic Charge range increased from 425 to 650.
This is too much of a buff and would make our champion broken, consider a smaller buff
Heroic Charge push distance is now how far poppy travels.
I personally believe this is not needed at all, this would just allow poppy noobies to have an easy time
Heroic Charge is no longer a click on cast but instead a target freely and move forward.
Like a shen e? I can see that happening, however, why would we need w movement speed if we had this?
Heroic Charge can push multiple targets or even an entire team but cannot go over walls.
I think this is a bad idea, lvl5 e is a 2s stun, we don't need this and will just make her easier to play or more broken
Heroic Charge base damage from 60 to 140 REMOVED.
Heroic Charge damage scaling changed from +50% bonus AD REMOVED.
Heroic Charge deals out 80% of total AD in physical damage and 50% of total AP in magic damage.
We don't need any of this, we already had a buff from 
which gives us a lot of magic damage, increase the ad and ap ratio when we don't build ad or ap, okay I don't know why you would do that. We need that base damage 60 isn't enough.
Heroic Charge terrain collision base and AD scaling REMOVED.
Didn't you just say this already? I don't agree
Heroic Charge terrain collision now deals true damage equal to 5% of Poppy's maximum health.
Absolutely ridiculously broken, the q has massive amounts of max health damage allowing us to solo tanks in lane, for late game we don't kill tanks so we don't need it. Would be fun though I won't lie about that :p
Heroic Charge terrain collision now causes a 10/15/20/25/30% reduction in armor, magic resistance, and movement speed reduction for all struck targets, lasting 4 seconds.
Ok, so you e the enemy adc on live servers and they get a 2 sec stun and die instantly. You want to 2 sec stun on a 10 sec cooldown (0% CDR) followed by scaling armour and mr shred and a movement speed slow for the 2 sec stun and 2 seconds afterwards. May I say you have been imaginative thinking about this xD. If we recall your previous changes we have true damage now so we wouldn't need ar mr shred, we don't need this shred anyway we can beat every tank if you know what you are doing. Movement reduction? we don't need this because whenever we hit someone into the wall we always use the q afterwards, which has a stronger slow making yours redundant.
Heroic Charge terrain collision empowers poppy with 30% damage reduction for 3 seconds.
We don't have a problem with not being able to tank enough damage I would say, even if you changed it to 30% tenacity for 3 sec I wouldn't say we need that either.
Keepers Verdict cooldown reduced from 140/120/100 to 100/80/60 seconds.
Keepers Verdict base damage from 200 to 400 REMOVED.
Keepers Verdict scaling of 90% bonus AD REMOVED.
Keepers Verdict now deals physical damage equal to 10/15/20% of Poppy's maximum health.
Shorter cooldown in wonderful I wish they would do it in game ;-;
Removing scaling doesn't really do much as you shouldn't buy ad anyway.
Love the last point by the way is very creative but is clearly broken.
I'm with 3000 hp, a fully charged keepers verdict would do 600 damage, which is nice I suppose but having a the best disengage tool in the game do 600 damage without any offensive items on such a large range is very broken. Just a shorter cooldown is fine.
I had a lot of fun reading through your ideas thanks a lot :)
I don't know if you play Poppy at all but she isn't as trash as people make her out to be. If you were in Riot's balance team and this was shipped we would see the old Poppy meta start up again which everyone hated. Looking through this reminded me how simple it is to make an average champion ridiculously over-powered, and Poppy has been very broken in the past so we must be careful with how we deal with her. Poppy is a very strong champion however you must understand how she works. Many people pick her up expecting her to be easy and simple like Garen and they lose and never play her again calling her trash which is very sad :/. Once you master Poppy you can easily climb the ladder.

This Korean got to Rank 4 playing Poppy every game, although he is now rank 54, Poppy is a strong champion to play and a prime champion to one trick because of her low pick and ban rate.
Thanks for entertaining me and please feel free to constructively criticise my opinions on your work.
