Next class update is confirmed to be the Assassins. So that means that these Champions are all viable options...
Personally I would expect big changes to and maybe (kind of expecting him to get his own separate big rework).
Who do you think will get worked on?
Doctor Jarvis2 votesKassadin needs to be improved. They took a lot from him over the years and never really gave back. I want him to be playable.
LordGeovanni1 votesWork on broken Zed
Ekko needs numbers and utility nerf
Evelyn probally diffrent play style
Fizz needs a numbers nerf or a full rework reds choice
Kat need s a passive rework cant have resets on already low cd high damage spells wtf design is that how is that intuitive.
Igotlazy2 votesEkko's got that coming next patch. These are reworks btw, actually changes to how their kits work. Not just number changes.
LordGeovanni1 votesekko needs to lose the slow on his passive its stupid and just there so his passive doesnt look like straight damage but it doesnt fit with his kit and his w looks like its only there to make his kit not straight damage assassin but reguardless an assassin shouldnt need a 2.5 second stun even worse aoe no matter how long it takes to set up they got a shit ton of damage
Igotlazy1 votesHis Passive has the slow and speed up component so he can overtake fleeing enemies and hit them with the returning Q. Trust me it's important (from a guy with 200 Mastery Points on Ekko). The Stun is actually 2.25 seconds not 2.5 and in 6.11 it seems at the moment that it's getting reduced to 1.75 seconds.
Actually here's the full change list so far.
Ekko: **Z-Drive Resonance (Passive) ** Lock out on same target increased to 5 seconds from 3 seconds.
Timewinder (Q): Initial damage AP ratio increased to (+.2 AP) from (+.1 AP) Damage after delay lowered to 40/65/90/115/140 from 60/85/110/135/160
**Parallel Convergence (W): ** Stun duration lowered to 1.75 seconds from 2.25 seconds
Chronobreak (R): Base damage reduced to 150/300/450 from 200/350/500 AP ratio increased to 1.5 from 1.3
I really doubt Ekko (especially his Tank Build) is going to be an issue after this hits live.
Arakadia1 votesEve is getting a VGU in the begginning of next year, so I doubt she will be changed. Ekko might need changes, depending on his balance after his nerfs.
I think these guys need major changes:
Fizz, Akali, Zed, Rengar, Kassadin, and Leblanc
Medium scale updates:
Shaco, Yi, Nidalee (and help lane nidalee), Kha'Zix, Nocturne
Small Scale:
Katarina,Talon, and Riven (If she is even an assassin idk).
