Played two games only, the most noticeable thing to me is how hard is it to actually kill anyone. Here is why:-
In 1v1 situations
No CC - yes she has a knock up but the only way to use that is to either move into the enemy's face or use E to gap close, but E only travels a fixed distance so its kind of hard to land where you want (but you can use E to move behind your target so I guess its fine)
No damage - regardless of your build, her damage is just so hard to unload onto the enemy, as mentioned above, she has 1 knock up, after that its up to your MS or if you build something with sticking power like
, without even a slow its impossible to get more than 2 autos before being kited by (if ranged) or just wasnt able to catch up to whoever decided just to run away from you.
Ult is useless - yes the tunnels last quite a bit but they would not be if placed at places meaningful, making her ult quite possibly the most useless in the game ATM
