No issues with heals. I'm a whm. I've healed it with another whm, with a sch and with an astrologian. Never any issues from that side. The weather parts can be a bit tougher to heal/more demanding if people aren't all following the mechs but they rarely will ever die. Maybe if I were still ilvl 130, then it would likely be another story. I likely wouldn't be able to keep up with ''unfortunate mistakes'' that cost much more healing....but as it is now, it's not a problem. Even while on the carapace while one healer is on at the end, one healer can easily heal it while the other dps's since all the damage is concentrated in one very small area. Any healer no matter the class can keep up with that (at least now for sure-I cannot speak for the event with much lower gear)
