I don't mind the 90% hit chance cap. Sometimes you hit, sometimes you don't. It's annoying when you go through many rounds of consecutive misses even at 90%, but I just buckle down and deal with it. The one thing that really does irritate me is the high resist rate against melee attacks. I made the unfortunate mistake of taking a dual wielder and a polearm guy in my party and oh boy did the end game game start to wear me down with its tedium due to how long it took to whittle down all those highly armored empire troops. Early on they did fine, but after I left the Vahnatai region their usefulness plummeted. There was a slight incline in power once I got the Flame Sword, but it was a little comfort and didn't even work against all the enemies due to immunities. The game is too biased towards Magic-Users.
It's no fun to clear a room full of enemies who take 20-50 non-crit damage per hit and have 300-500 HP. It's even less fun when you keep doing it dungeon after dungeon, room after room.
