However it remains the case that improving the Abbot to be better than the original version would give a higher payoff in gameplay and product quality than spending the same manhours on new quests (especially low-level quests).
That will remain so until the level cap moves on, and could be further aided by some minor improvements to Abbot raid loot. (Particularly, adjusting items to be attractive to both casters and warriors, such as Greater Abjure Focus on Enduring Conviction and Paralyzing/Weakening on Staff of Petitioner. Plus make the robe, helm, and belt not suck)
