So, I've done this a lot, and its not really "tricking the system", it is helping the FATE, too. If you are a PLD with aggro, other classes don't have it : D

I haven't been able to substantiate this, but I think that you only get massive amounts of credit for spamming flash if you become the PRIMARY target on a lot of mobs. You can't just flash everything that already has Enmity on it once, get green triangles and walk away. That being said, with average gear I have no problem picking up a bunch of mobs then spamming heal/riot blade until they are all dead, then repeat.

This DEFINITELY works though.
