A lot has been said about Kettle already. Some buffs that would help him have been discussed in the Hero Thread.
My thoughts:
Could be a great hero, but needs some tuning.
- Average speed would fit his specials better.
- Second part would be better if the DoT would become uncleansable or would involve a wither effect (all enemies -400 def).
- Third part is a b*tch, but can stay. Maybe change the percentage chance of his passive to 100% if third part is activated (90% damage to all plus accuracy drop). Or combine wither & growth:
Wither: All enemies get -400 defense.
Growth: All allies get +400 defense.
