Suffocate is a joke. It's so not worth 3 points. A power with the duration extra should cause the target to catch on fire or something and save vs. damage every round. Not cause them to pass out after 20 rounds.
Interestingly, one of your problems in the fight (dispersed teams) seems to be making things run much faster as a PbP. Since the characters are split up into 3 teams (1 PC+1 NPC, same thing, 2 PCs+NPC), Toki can post something as soon as one group is ready to move. Ie, everytime Mark or Ryan posts, if Toki's around he can update with the results and partner's action. And if he isn't around, there aren't going to be updates anyway. So things can move alot faster with you guys split up. But they seem to be more likely to move faster into your defeat.
A 45' RADIUS blast is a bit large to casually toss around indoors, I'd think.
Black Heaven fired his fatigue power instead of moving, so maybe James could still grab him since he didn't move.
HH, I'm not sure the irony in your comments about the difficulty is coming through all the way. Sarcasm is harder to pick up on the Internet, remember. You might sound like Andrew to someone.
The gasoline still wouldn't have helped actually. Maybe the 2 people you dropped in on would be on fire. It's the 2 teams fighting elite adversaries that need the extra firepower.

But if you'd devised a systematic plan based around transmuting things to gasoline, then maybe you'd have something. Force the sprinklers to go off first, to extinguish any existing fires. Cut the power. Then Ryan uses extra effort for AoE building -> gas. Strength and his buddies might be more inclined to go quietly if they all were ready to go up in smoke.
You guys aren't good at anything really. I was going to say hanging out - most of the characters stopped whining, and the Legacy team isn't really into gossiping. However, when you hang out, stuff gets attacked, so that's out. Maybe upsetting Jimmy. James, Ryan and Mark didn't get along with him initially, and in some respects still don't. Putting Anika and Jimmy in the same room is like mixing Cesium and water.
Rave's Selective Obscure delayed the fight 5 rounds? I didn't think it was all that effective.
