Tanks are heavily underpowered

Ashe's Q is one of the strongest damage steroids in the game. Tanks always died quickly to sustained damage, but I think it's really over the top right now. Ideally, tanks should at least last long enough to give their team a chance to help. I only see that in Twisted Treeline nowadays.

On that note, try Sion jungle in TT. If you focus on farming and buy only tank items you can dominate all game through sheer bulk

Because crit/AS build ADCs spamming autos that deal 1000+ damage every half second or so kills a lot of things.

Ashe's passive lets her pretty much build all crit related items (and maybe a bloodthirster) and your armor won't mean anything once she's hitting you for over 200% dmg per auto after the first.

That's literally impossible unless you had no HP items and the Ashe was way more fed than you.

Dying to ADCs as a tank is intended
