It's pretty terrible against most tops. She can kill a lot of the mid laners though.
No it isn't, she has a passive armor shred that lets her build against whoever she is facing in lane and still do a lot of damage.
To get that armor proc it requires a commitment usually of 3 hits. It's not a frontal trade like many others.
she loses most top fights due to her passive having such a long cd. Makes her trading literally only good for 1 for 1 shots. Tops usually have gap closers, its not going to be a 1 for 1 shot.
Hence the she can BUILD AGAINST whoever she is facing to avoid taking punishment when going in to trade. With smart usage of her E she can poke at other melees without them ever getting the chance to retalite.
Going to church doesn't make you a Christian any more than standing in a garage makes you a car.
Harassing the enemy out with her E requires you to be in lane first. If you are not enjoy the lvl disadvantage and being harassed before touching the cs. She suffers greatly from being behind in the early lvls. She can mid due to the fact if you go against a karthus/tf they don't have much follow up dmg right away.
Hitting lvl 2 after the enemy top lane is not an option for her.
I don't always lose, but when I do it's purple sideu!!!
