Paladins rock at aoe threat, You can flash like 20 times straight to hold agro and can continue holding threat with fast blade, riot blade combo followed by flash. The snap agro from the first 20 flashes you do will set you far ahead of everyone else, which gives you time to get mana back through a combo. On a warrior your aoe threat, though people say its good, is not sustainable, unless there is something I don't know about it. But, in theory you can cast flash 4-5 times, then you can over power until you are out of tp. After that you are waiting for tp to regen or you are swapping to a single target / tab rotation which kind of sucks.
