Healers that don't want to DPS are like DPSes who refuse to move out of AoEs.

[Kit-Kat]

A big reason this game has so many bad/lazy dps in particular is predominantly because they know that any slack they have will be picked up by the healer 95% of the time, and even if things die slow, the first person to get blamed is the healer. As a dps it's admittedly very demotivating to see the healers dpsing since then I pretty much have no reason to be there. XD Admittedly it's why I've swapped to tank, I can mitigate, stance dance and care about my damage without feeling like a useless third wheel. After all, no one cares what the actual dps do, right? Even if one of them does very well, the healer using macros is gonna get credit instead.

A big reason this game has so many bad/lazy dps (or any role actually) in particular is predominatly because they're whiteknighted for being bad or not playing their class properly, nor caring to improve, getting babysat by the rest of the party. They're praised for playing in their own 'style' with a pat on the back while affecting others. I do encourage you have fun when you play, be it the way it might be, but please, this is not an offline game and you're not queueing alone. I don't know if this is just me or really a minority here, but our playerbase is too selfcentered with the me me me attitude. That feeling when you give your best but someone is like "meh, why would I, someone else will put the effort for me instead".

Also, a healer dpsing isn't taking your job, it's helping you with it since they actually can do both. If a BLM/SMN heal was as strong as a healer class spell, you could see them supporting the healers if needed, but the 500 heal vs 5k heal is nowhere nearly helpful at all. On the other hand, a healer's DPS is really strong and high enough to contribute to damage. Not nuke dps, but constant dps.
