Please. Don't.

I personally think by the end of Heavensward, you're pretty much ready to tank any dungeons beyond that point barring any mechanics with different coat of paint and actions that are still waiting to be unlocked. They teach you nothing else new aside from having new buttons to make your life easier.

If you still want to practice in lower lv dungeon then kindly please queue into them directly. Ilv cheeser is up there in my lists of few things that potentially ticks me off, but I also don't pay your sub so whatever.
