Melees beat casters in 1v1, yes, even SMNs. A lot of the melees complaining think they should just be able to auto-attack and 1-2-3 casters down and win. When caster's sprint, they forget they can Sprint themselves, or negate the caster's sprint all together.

Melees have burst of their own, self-heals,stuns, fetter ward(mnk/drg), etc.

Its just now they actually have to try to kill SMNs, so they complain.
