"can an ot take my time gate pls" - A12 question

[Ninster]

So I'm joining probably some several hundred other procrastinators in farming A12N for my drop tonight and there's a SMN that brought up the title quote which made me scratch my head enough to make this thread.

Said SMN was in mix of Augmented Shire/Alex Savage gear, clearly outgearing me, so I'm wondering is there a reason he could ask for a pass on a supposedly dps-only mechanic? I've never heard of a strat where a dps passes on the timegates on purpose, but I don't spam A12 much either and I've never been in it's Savage counterpart. I know it's possible for OT or healer to jump in one if a dps is dead or whatever extraordinary case, but I've never heard of this.

So as SMN, do I still need to be doing time gates or is this guy/gal on to something I'm not aware of? Funny enough, his request went ignored so me and a monk had to double team the add that was left alone, much to my displeasure.

EDIT: This was brought up at the start of the run, so low MP/weakness/etc wasn't a factor.
