Galios Q is overtunned.

i normaly never say this about a reworked or new champion, but this guys Q does insane dmg just at rank 1 with thunderlords. if you are not careful 1 Q as a mid laner will chunk a good 40% or more of your HP even as a top laner its still going to be chunking you very hard untill you get some defenses. the ticks and duration on it is so short that it will do its full dmg before you can escape as long as its landed dead center, and thats the real problem with it. the duration and ticks should be a bit longer to give people enough time to escape the dmg. if he gets rylais its just rip for any mid laner. to put it into perspective:

dmg = 105(+60% ap)(+40% ap total tick dmg)(+9% max HP total tick dmg) + thunderlords. a typical midlaner only has 572 HP or less if they buy dorans. Again, the main issue is how short of a duration on top of ticks it has. 1.5 seconds to do its full dmg. lvl 1 no boots you are not walking out of that if it hits you center, so all it takes is one misstep when you are trying to cs and you are going to get chunked near half your hp. the skill also scales very hard, stupidly hard infact. so its going to be hitting you even harder as the lane goes on.

but even if you dont get the full tick dmg one of the two projectiles is going to be hitting you for 60(+60% AP) to 200(+60% AP). and its not like its easy to dodge, its basically two diana Qs coming at you from a tank that gets even more dmg by building MR...
