Hi,
First of, I totally agree with the Galilea nerf. She was way too strong and had (has) a lot of abilities that make here one of the most hated opponents. I also think MOBA games will always need character balances.
So far no worries… The problem I have is with all the people whining about pretty much every Hero. Marquis isn’t OP in Meltdown. Maybe your main hero is an easy target for him, but that’s not a reason for a nerf. Everyone has a favourite Hero, and they all have a nemesis. Deal with it.
