I just beat Grym for the first time last night, and two things struck me about the fight, it would have been very different with held actions; and it reminded me a lot of MMO boss battles (in my limited experience)

I still thought it was fun, I like when fights have a puzzle aspect, but I didn't particularly like "wasting" turns with people, especially knowing how different if would have been with the option to hold an action, even it it's just a move action to get off the platform.
