Assessment on new MF: Requires a few tweaks to Strut.
I've tried out the new MF a bit, and I can't say that she got all the buffs she needs. There's still room for improvement on her, and here are some things I think would help her out, without affecting her damage (which Riot won't take player suggestions on).
At levels 11 or higher, Strut is no longer removed by minion damage and, when you take direct damage, lasts 1 extra second before being knocked out.
MF could really benefit from minions not knocking out Strut in mid-to-late game, as this would let her split-push much more easily. She wouldn't have to worry about a random minion AI screw-up knocking out her passive. The second half of the change is one that makes MF less vulnerable to assassins and jump-fighters, giving her 1 second of leeway before she loses her speed, and also making the active on her W not so worthless against enemies who are groping her.
These changes would only activate at levels 11 or higher, though, so as to not affect MF's early game, and give lane opponents the same ability to outplay her early on.
