Locked out of future MSQ progression?

Please go ahead and tell me which competitive leagues have their teams pug their members while you're at it. I want a good laugh.

You're actually helping my example. That's exactly what happens a lot of the time when you queue into a pug in this game - you fail and you wipe and people get salty and upset and you disband after half a wipe on Ravana HM. And that's if your pug members didn't insta-abandon as soon as the option became available.
If you want relative certainty of clearing content, you come in pre-made. You say you don't want bonus. You put gear restrictions on your PF. That's your pro league.

If you get a full party, you can queue for most duties without abiding by the required party make up just like how you can play by your house rules if it's just you and friends in the backyard. You can go in full dps, without healers or tanks - this is you agreeing to play without a goalie. You're fine with it, sure, maybe the rest of your party too. But you shouldn't be surprised when you wipe because the game wasn't designed for it and suddenly there are other people's rules to follow. You're playing someone else's game, after all.
