RE to Boss battles: Yeah there should be a save point at least near the floor he/she/it resides? I'm sorry to hear that about Arc, especiall since I wanted to play the game :(.
RE Parties: I frankly don't care what happens as long as I get
one at the end. You know what? I just lied. Like Dincrest said, when they leave and make a return, they sure as heck be at a decent level or near the main hero's level, not at level one or 20. If that happens, then they really are no use to me unless I grind, and I don't level grind because I don't have time to do that.
I think the worst offense in boss battles is the point of no return.
I'm sure several people were screwed by Final Fantasy Tactics by that certain boss battle that was a huge pita. I know I was.
So much truth in that. I remember my first run I was barely getting by each mission, but then came missions with continous battles...fogeddabout it.
