Had a game just like this yesterday, 4 melee and Ryze vs Ashe, Vel, Xerath, Jinx and Varus.
We won but that's because we could just build resistances and CC them to death but the early game was horrific. The damage charts are funny.
now just remove the dodging part.
when facing a poke team comp your team can't dodge shit, when you're a poke team comp the enemy all has split second reaction and dodges nearly everything
Then the melee gets resistances and just dives face first in, results depend on teamcomps after that.
