Funny to watch how players speak about balance in PoE on Grim Dawn forum. Grim Dawn is awful in terms of balance. Game has a lot of OP skills which is must have if you want to make decent build. Game has totally broken core mechanics. A lot of affixes are total garbage. Game has crazy amount of flaws. The only reason why balance issues do not concern you is abcense of competion.
A lot of players cheat or dupe items to test their builds.
GD have better graphics but absent atmosphere.
So, I can continue but obviously the only difference between this games that GD is single player game (maybe best singleplayer ARPG) while PoE is competitive online game.
All other things does not matter to be honest. I hate skill system in PoE but I hate a lot of things in GD too.
