1. You have to take into account that each crystal would be computed against defenses individually and not as a whole.

2. Her mana costs. It's the point that most of her skills are actually  a bit OP since before she uses any of her spells, you'll have to first think, "Is the speell worth the mana" or which spell should I use since I basically could only do one or two. But in the late game, when she has mana items to compensate with her costs, you'll be wrecking people up.

3. In the league, you always have to think before you act. First of all, why would you tower dive someone you know that could immobilize you and look at you like a moron while you're being hit to death by their tower. Second, As Bruiser(intended for V2), your main priority is cripling the enemy's carry, and that's what the ult is for. If you would look at it closely, her V2 ult is the only hard CC she ever have. Most of the other are all more on utility base, which in my opinion, is actually visible on most bruisers.

4. The heal was intended to be only from the damage dealt to champions and not include minion damage, but it still does damage minion, it just doesn't heal her. I'll put it up ASAP.

BTW, Thanks for the Feedback :D It is much appreciated
