Elise needs a buff
I've been playing around with her all over and she is very weak in situations where she's supposed to be awesome. If you think about it, her full combo to get a kill is a full two ability bars long.
(start in Mage Mode) E > W > Q > R (Spider Mode) W (atk speed) > Auto a bit > Q to finish > E (if you need to cheese an ability. And sometimes your target STILL doesn't die. Whereas you can be Yasuo, Zed, Ahri, Kayn, Irelia, Urgot, Darius, etc, and do way more for far less effort.
It's very sad that such awesome mechanical champs that take thought are left so far in the dust for champions you can spam or auto to win. Last I checked, Elise made for "dem LCS playz"
