Diana's Q needs to cost some ACTUAL mana

There is NO reason that ANY « Assassin » archetype should be allowed to be able to spam a WAVE-CLEARING ability, absolutely NONE, ESPECIALLY for the amount of damage that it dishes out, and EVEN MORE SO due to the fact that it costs Diana ALMOST NO MANA AT ALL to SPAM it all day. Mana-costs need to be added into her kit (comparable to that of Galio's & Malphite's mana-costs), the AoE needs to be changed to Single-Target INSTEAD of AoE, and her base-numbers are too damn high, also need to be dropped. Also, Riot's balance-team is full of dumb-asses, and there needs to be at LEAST 12 bans currently (per team) in Draft-Mode due to the Balance-Team's inability to stop breaking everything. They also need to be fired from working on Balance or designing items or creating new champions.
