The problem with MCH utility is that none of it is really needed right now. Unless you've got a really bad healer overhealing like crazy, MP/TP regen isn't needed. The damage debuff either. None of my utility abilities have they saved us from a wipe or really helped anyone else. Yes, I can give that DRG doing who ran out of TP some regen to keep going, but at the cost of my turret damage which ends up not being a huge gain as it should be because you're giving up a good 13-15% of your dps to do it. I've seen SMN battle Rez used much more.

And the whole "supportdps" (not sure what making it one word is supposed to actually accomplish) argument is still lame. Other classes also bring a good amount of buffs and debuffs for the party that are arguably more useful.
