Unfortunately someone with a skip might still get a surprise (e.g. Holminster) but that would help.

Expecting a tank to know how their mitigation works and when to use them really isn't unreasonable, no one is even asking for a perfect use- just some recognition that they can hit those buttons at all when they are likely most needed.
I'd disagree with sentiment. Unless you're wall-to-wall pulling at those early-to-mid levels (which if you're just learning how to tank, you're probably not), I can easily see someone noticing no need whatsoever to use their main mitigation abilities on single trash packs. The change happens precisely when you both: A.) Get to higher levels, and B.) Wall-to-wall pull. For developing tanks, that may not be happening period until they're at a higher level, and all it usually takes is an actual polite recommendation to go ahead and use some of those mitigation tools on the trash, because when we pull multiple packs you'll find that the trash actually does more damage than the bosses.
