This. Which is a major flaw in the way this game allows for people to queue up or join friends in an in-progress run. Not only for ST, but for any type of dungeon. If they have a role lacking, they cannot directly invite you. A gamble of getting in is joining using the in-progress queue. However, the in-progress queue pools you up not just on actual in-progress runs, but also in the overall pool.

Trying to join an in-progress run as a tank, and hopefully ending up in the correct one, usually comes down to first turning down 10 - 20 or so fresh runs.

Therefore simply locking out after a few turndowns of pops also isn't a great solution on itself. If SE would do that, they should at the same time also come with the possibility for players to invite friends directly into an ongoing dungeon group.
