How am I supposed to play Evelynn?
I mean... I see her all the time carrying games, whether on my team or the enemy just ganking all the time and pretty much winning early, and then carrying from there on being an unkillable death machine. Then I go and play her and every time I either A. can't win a single gank because people are either too mobile or I don't have any damage(or CC), or B. I win early game hard with my team and go on to be bursted before I can even finish my Rylai's and then shut down. Even if I try to play safe and let my team go in first then followup, I always get bursted and focused, and even if that happens to another Evelynn we usually win fights, but not when I'm playing her. Its like I just go down in a second and then they move on to the rest of my team.
So how am I supposed to play Evelynn? I try to build the best I've seen while still sticking with some safety if I'm doing badly- usually Runic Echoes>BotRK>Rylais>something else(plus boots which are usually defensive like Ninja Tabi), and if I'm doing bad I'll go to Zhonyas, Abyssal, or Maw for defense, sometimes just Randuin's or Banshee's if I'm just feeding) - and during laning phase I tell my team to pull and I gank as much as possible without putting myself super behind in farm. After that point I usually just turn to crap and I don't know why, its like I can't do anything after that point even though I see Evelynn's carry all the time.
these are kinda core items she procs sheen so easily, and boots is for getting around works with her W which comes in handy. In lane it's better to max E though it won't hurt you much to do the same jungling too it gives you some decent ganks when ganking well helping proc thunderlords or surge, or death fire grasp idk which you use. As good as she is at ganking she does just as well at split pushing, she can take an entire tower if you leave her alone with a sheen and some minnions under tower.
