I know I end up using "wait" a lot as well, often either
a) Stalling in a "safe" battle to use buffs or heals for the "Receive Heal #" or "Deal Heal #" or "Get Buff x times" type missions
b) Letting a specific (often weaker char) get kills on a target for "Kill x [enemy type]" missions. Sad that DoT's dont count, but it makes sense that would be difficult to track. (Kill X is especially difficult on Maid, since most of their damage potential is DoT based; French Kiss and/or pink feather duster's DoT)
Sorry for no analytics; just not a fan of games that do that. Very grateful for the opt-in approach though. Seen games that get screwy performance with analytics on; or kill my limited shared bandwidth. I play slow and weird anyways....
