It really depends on the tank and if they are a mentor or not. For the most part Mentors will help with the exception of a few trolls here and there. There's only a few dungeons, mostly old ones up to lvl 50t hat have multiple rooms. We tanks like to do speed runs being we have other things we try to accomplish. Normally if I'm tanking and someone ask I'm willing to if the group agrees. Otherwise I advice to do hunt logs ( Job / Company ) for fast exp or fates while in queue being that now you can have choco out and makes them go faster. You can also ask help in the novice LS for a tank or ask an FC / Friend to tank for you a few runs.
