I've fought a few Galios and whenever I do they seem nigh unkillable and put out pretty good damage with only RoA as a damage item. What am I or my team supposed to do? In my last game it took my entire team to kill him and most of the time he would just walk away while we whittle him down and still escape.
Run for your life
Really a large portion of damage comes from where Wings of War collide. You wanna avoid that. if you think you can't run back out of it, it might be wise to run towards him instead, depending on who you are. If youre say a riven, running towards him when he uses his Q increases your chances of not getting hit by the % max hp shit, and then you can dash to the side before he uses Justice Punch.
Id really need to know who youre playing him against to give you any further advice
Well if youre playing Rakan, dont expect to kill galio.
Can't give much advice in top lane against him since I haven't had a chance to try that matchup. I do know it's almost impossible to die to a Galio as 
tho. He's like a free kill waddling towards you while you deal with his team around him.
This was before bramble vest was implemented, of course. Not sure how that'd affect it.
