Galio is by no means OP but could be tuned a little bit.
Galio is definately not OP, but I'm not so sure about the way the Q works. Currently It does 60/95/130/165/200 + .6 AP Scaling.
Doesnt sound too bad eh?. The problem is that if you get hit by the point where the 2 wings meet. you actually take that damage X2.
This breaks down to 120/190/260/330/400 Damage + the .6 ap scaling calculated twice.
The tornado damage over time is good against tanks and thats what it was designed for, but The initial smack can be pretty devastating against squishies. especially if he gets a lead.
I kind of think that the damage on the initial smack needs to be toned down because 400 damage before scaling on a 3.6 second cooldown seems pretty busted lol. (it gets down to a 6 second cooldown and with 40% CDR that comes out to 2.4 seconds reduced on the cooldown and 6 - 2.4 = 3.6)
