....
the only peeps who might tell, some NORMAL duties are difficult or too hard, are the ones with some kind of disability - I'd understand that tbh.

all others mimiming, telling like "I want to relax, it's a game", are just lazy or unwilling to learn.
U're like 4-8 peeps in a duty, just ASK If U didn't get any mechs or something.
Social anxiety .. it's a MMORPG, so I won't let that count tbh.

and like some others said already, them duties are optional. so skip them or play them duties with Ur NPC friends.
