It is a very flawed concept, especially considering pld is meant to be a tank job. However since making this thread I have successfully tank healed all the job final quests. The biggest down-side for me, aside from mp which I have to manage well, is the massive amount of threat I build getting the full effect of succor. Apparently, as discussed in another thread, succor is meant for tank threat gen but without the over-healing that use to exist, 9:1 succor heals for 0 as tank or a party member who could benefit from the heal is too far away. Even a war couldn't keep the dragoon final boss off me after the wyrm died and we really started focusing on him. That being said I will now try some -enmity melds, and attempt a real boss fight starting with Ifrit. This should stress overall threat gen over a lengthy fight, as well as see if my throughput increases due to the nature of the fight, mainly stationary from a healer pov.
