Many had already stated, "Evie is Broken".. "But why that?", I asked, when I was yet naive and it didn't took me long to realize..
Evie has two mobility skills, Soar and Blink, allowing her to quick get on enemies backs, kill a few and get out, many games I played where good Evies didn't died ONCE, simple because, even if they F.ed up they could just get out of the situation, shruging away like "Welp.. Maybe next time!".
But the thing that I feel it's the biggest problem is the Ice Block, I don't mind the mobility, a good Androxus can settle things up with her with no worries BUT the Ice Block is where it is.. Most Evies uses that card that regen her HP while in Ice Block adding to her increadible survivability with 2 mobility spells (3 if she has the Wormhole card), a life regen and 2 slows (direct fire and ult).
My suggestion is when she freezes herself in her Ice Block, make so wih her cooldowns aka make her cooldowns also freeze, example, let's say I need 3 seconds for my Soar to be ready to use, then I use Ice Block, as soon as I get out I can Soar away BUT, in this scenario, the Soar would get stuck on 3 second and would only start counting back after I break out of the Ice Block, I also increasing her HP to 2000 since this nerf would be huge to her.
It's just a suggestion.. I dunno.. Been feeling like she's a character that is too hard to put down, even if she cain't aim properly and kill anyone it's very easy for her to survive everything.
