My main problem with Qiyana
Lethality Builders / Assassins, in general, should not have CC.
The idea of assassins is that they are high-risk champs that need to get the drop on their opponents and full combo them before they can react if you want to be successful.
The problem with Qiyana is that she is a team fighter with Assassin damage. Her kit has so much multi-target CC in it that you would think that its damage would be lower to account for it, but nope. Assassin damage.
It kind of pisses me off.
