Shaco, Backstab, Sheen, and Thunderlord's - Extreme Frontloaded Power

I've been keeping this kind of hidden because I wanted to abuse it, but considering Riot is trying to gut all of his damage I think it's worth mentioning now. It's been about three patches since this was implemented.

Thunderlord's is supposed to proc after three attacks- on Shaco, this should be two autos and an E. The actual case is a bit more complicated than that. If you have an AD Sheen item (Sheen, Trinity Force, or Iceborn Gauntlet) then a Sheen proc + Backstab actually counts as two attacks. This doesn't apply to Lich Bane.

Q+Backstab+E with Trinity Force will proc Thunderlord's. Q+Frontstab+E with Trinity Force will not. Q+Backstab+E without Trinity Force will not.

This is a main source of Shaco's burst for the past three patches. Fix that bug and you won't need to remove all of his Q damage scaling in order to nerf him. It's just a bug, that's all.
