Most MMO's doesn't even have healers, you gotta take care of your own healing. And if they made healing diffuculty higher than it is now, then a lot and I mean A LOT of people would struggle. Hell, people struggle already now. Yesterday a guy asked a tank or a melee dps to do the pink color in 06s, because he said there is ton of damage to heal when 1 healer is inside the thing that kills the wind spirits. It's just 1 aoe and it's pretty easy to heal...
