So as a main lvl 60 PLD with ilvl 190+ gear, it pains me to see a healer stand around doing nothing when I'm clearly near full health and don't require any healing for at least 4-5 seconds. (Even more so when fighting bosses and they are casting an attack)

I usually find this behavior in my expert duty roulette. Sometimes I inspect the healer gear and they have 190 alex gear, which means they obviously should know how to dps and heal.

I understand that some players religiously believe in the phrase, "I'm a healer so I only heal." which is fine if that's what they believe. I guess I'm just looking for answers as to why players who play like that find it fun? I've started a healer and I find it so much fun having to balance watching when to heal and deal damage in between.
