Holy requires more concentration because it doesn't have fast heal in form of PW:S and Penance + hasted flash heal. It also has less mana and goes oom way faster. It also has SoL procs which you have to utilize smart. Now you can throw any argument you want, the fact is that disc has less spells and faster heals and mostly heals tank(s) and throws PoH when tank is fine. Holy has to manage mana / sol / and also time when to drop PoH so it isn't wasted on overhealing. Besides, this game is so ridiculously easy and the amount of concentration taken to play any of the 2 specs properly isn't larger than noticing when the green light is on at the traffic light.Originally Posted by darkdestiny
