The fact that no one on the balance team seems to actually /main/ a healer. A lot of complaints are being made about difficulty but frankly I don't think we can actually tackle the issue of difficulty until we actually have someone who understands healing at all levels in this game to both design for those classes and to then go on to design encounters to complement them. Hell they don't even need to hire anyone to fix this issue, just tap the top healers for each job and have them do some consultation work. Or, you know, actually spend more than five minutes in the healer subforum. It can be a dumpster fire at times but most of the proposed fixes being put forth there are actually really, really good. Regardless I don't think we're going to see any increase in difficulty until the developers start to understand how healing actually works in this game.
