Miste:
Well a healer not dpsing is not comparable to a dps spamming one attack. More like a dps with a subpar rotation.
And just so we're clear. I understand a lot of what people are saying. I'm always DPSing as much as I can, and it's not uncommon for me to dps more than anyone else in my party. I enjoy it, I just don't expect others to feel the same way. If they don't want to dps in my 4man content it's not a big deal. They can have fun and I can spend an extra 5 minutes in a dungeon pulling bigger or dpsing more while eating mechanics etc.. Whatever floats my boat and keeps them on their toes.

And yeah some people are rude. Personally I have a beef with DPS pulling instead of the tanks (usually to speed things up). Especially after the tank is uncomfortable and asks the DPS to stop. Imo this is symptomatic of the greater issue brought up in this thread. Which is that people don't enjoy their dungeons much and just want them over with asap.
