At least she doesn't have the kind of shitty mechanics that make people want to autoban her regardless of winrate ala. LM /Tracer - if they buff her she could be in a solid place. Right now she's almost a trollpick though, played a few games last night and steamrolled every time there was a Chromie on the other team (luckily didn't end up with any on mine).
30% winrate is a little absurd - have any other heroes ever dropped that low?
I like what they've done with Falstad. I was a bit confused by the changes when I skimmed the patch notes, but trying them out I like that they've gone out of their way to remove the strict division between his mage build and his AA build - especially since I hate his mage build, which was winning out before the patch.
On the flip side, I'm disappointed by the Arthas revamp, I can't really put my finger on it but he still feels extremely underwhelming.
