No real hypocrisy happening here. "You pull it, you tank it" is just a straight up awful mentality to have regardless of your views on rescuing a tank into a mob pack.
Both of which are a non issue anyways if you just pull everything in the first place like you're supposed to do.
Back to the main subject, I personally will ask on chat for bigger pulls if the tank is single pulling (or just bail depending on my mood).
That said rescue is pretty useful and I tend to use it quite a bit. I always keep an eye out for people not running away from Ancient Flare and rescue them, particularly if they're a sprout. Usually saves them, rarely doesn't.
Boss roomwides are also a great use for rescue if the ranged DPS are all the way in Narnia and I placed asylum around the boss. BLM kinda sorta has an excuse if they've placed their leylines, but SMN/RDM have no such excuse and neither do the ranged physical DPS, so I'll just rescue them into the bubble. If they run away again oh well, not my loss. I won't waste a GCD on them (although maybe an ocgd) so if they die it's their own fault.
