Yeah, there have been a couple spots where I've had to re-do the fight 3 or 4 times, and I'm not even that far along in the game. The big critter on the broken-apart freeway overpass was one, and Tiamat's dungeon where two medium-sized critters (the ones with ablative armor) were pretty tough. Looking forward to facing Tiamat if I can ever remember what I've been doing, and how to get past the final door in that dungeon.
