DPSing as a healer

[Reinha]

PLD at lvl 50 sync lmao.

That said, even though PLD doesn't really have much AoE even at lvl 60, this can be off-set by the fact that PLD has ridiculous amounts of survivability in trash pulls, where healer DPS shines the most. A PLD can keep him/herself up through the entirety of a trashpull without healer intervention unless the pull is extraordinarily big, and even then, a regen or two is the most intervention the healer needs to do. PLD's lack of AoE DPS in trash is made up for them letting the healer be in Cleric much more.

And all of it is wasted on the healer that just stands there overhealing when the PLD could sustain himself...

i can tell you i tried tanking and it is less work than staying around watching HP bars and being ready to heal.
so where is the rant about tanks? just pressing 1-2-3 combo, spamming one button for aoe and sometimes popping a cooldown...

A tank that is using every GCD is doing more than the healer who is "watching HP bars and being ready to heal". If the tank was putting in equal effort as such a healer, he would just be standing there with mobs hitting his face watching enmity bars and being ready to take back aggro. That's called minimum contribution.
