I know people are gonna maybe complain about this being reported, but, it's kinda lame.

White Mages, basically anyone, can have a low level run around and tag a ton of beasts, monsters, whatever, nearly double their level while spam healing the lower leveled player. The upper level player gets all threat from the low level players tag, and once all the monsters group up on the upper level, they can do 1 AOE and one shot all the monster. The lower level gets full XP from the monsters killed because the level 50 isn't in the party.

Don't say I'm stupid for reporting it. It's just kinda lame to see a ton of 50 WHM's running around with level 10's, having Regen on them, and watching them holy spam the heck out of the mobs to give the level 10 full XP and ding 12 within 15 mins.
