why do my fellow whm's forget to use dia in eden raids when i seem to be solo healing

Are these new AST's I occasionally see in crystal tower roulette? why did they pick up the job when pretty much all AST's retired when 5.0 hit.

As a followup, SCH's, when did you guys stop wearing your nice hat? I only ever see it in crystal tower sch's now

Why do some healers think even the slightest overhealing is a bad thing? 1 more glare/broil isnt going to make a difference particularly when exdeath casts whitehole and wipes half the party because they were 80002/81016 hp on a farm

can my co healers please explain why they swiftcast raise someone the person who I'm rezzing slowly because they were taking so long
