Of course it can happen to get pulled into a CC hell, especially if you don't have purify up and get caught. In CC you're not supposed to keep taking punches all the time even as a tank especially if your purify is gone. You'll get mega punished at high level because that's already considered overextension. Relaying through the team to spread the damage and cooldowns is the ideal situation you want to go for, but sometimes it's not always possible.

And yes sometimes you can't do anything about it, because your team loses, things snowball, or the context makes that yeah, you're done for. Sometimes you also have to accept that you got outplayed by someone else.

( I still want to make a disclaimer as usual that I'm not talking about polymorph, that thing literally makes everything I said totally moot )
