Healing is a bit over the top at of this moment. Not sure how the expansion gear reset will handle healing but since the second coils of bahamut healing has shifted from being the hardest job to argued the easiest job. The ability to quickly get people up after a round of aoe and burst healing has significantly gone up with gearflation. Overall healing potency seems a bit high since most healers hit I level 90+ over a year ago. It least healing is newbie friendly now and with 3 healers in the game they may start to disproportionately be more then 25% of the overall playerbase with the normal paradigm of 1 healer, 1 tank and 2 dps. Id say more along the line of 35%-40% of people will main healers since its now the easiest of the covered roles in ff 14 now. Tanks will still be a huge issue now and with complexity being cranked up a bit for dps its no wonder so many people are changing mains to a healer now.
