I'd love to fill in your form with precise details, but there's maintenance right now (hopefully fixing this), but I can say for certain that as DRG/RDM meleeing adds when there is no damage being done to the root by anyone, I get 0/0 exp/bayld. If I cast Dia II on the root, then kill adds, I get up to 4/2 exp/bayld. If other people come in and attack the root but I only attack the adds, I get up to 1500 exp, 750 Bayld per evaluation. I can get similar amounts of exp if I am killing the root and others are sleeping/killing the adds. I never cure myself, only use barspells to activate healing breath, Jumps, auto-attack rounds and WS, and the occasional smiting breath.
However, when I try the same thing on BLM/RDM my exp/bayld is terrible. I try enfeebling the mobs, including sleepga, curing allies, nuking mobs, nuking the root and of course buffing myself with stoneskin, refresh, haste, protect/shell. Exp varies wildly between lots of no exp/bayld, and up to a huge 200 exp 100 bayld. This was even after the update where enfeebles etc. were supposedly fixed. Though I didn't try BLM again since I got Reive Unity KI. Does this make any difference to the amount of exp/bayld earned????
