Cooldown Reduction isn't a valuable stat on her, as it is wasted if you get a reset, which is what your kit is about. The Assassin mastery is better in some cases where you have to assassinate more than contribute to a big team fight (ie: you have Amumu on your team). Corrupt Potion isn't favorable, I normally start either Doran's Shield vs single target enemies, like Cassiopeia, or Boots of Speed, finishing off the remainder of my gold for potions. Wittle people down with Q until they are at about 60% hp or lower, and if you know the jungler isn't there, you can QEW trade vs some mid laners. I max Q, then W. Thunderlord's is REALLY strong on her. Use it as much as you can when you QEW trade.
