As a tank, notably a PLD, who spams Duty Finder, I get all kinds of complaints from other players who either don't want to tank themselves, don't have a Lv50+ tank, or just have the need to complain about everything. Everyone is labeled bad to someone in some form.

I pop my CDs often. Heck, if the DPS are melting down mobs, I pull more. If I pull a LOT, I pop Hallowed Ground. Problem is, people would spend more time calling me stupid rather than using that time to dps. I'm not sure how it's labeled "stupid". Then, I get people who complain that my dps isn't contributing enough because I'm spamming Rage of Halone combo. If I have two BLMs who are burning quick or sprint ahead of me and start pulling and attacking before me, then yes, I will spam Halone in rotation of each mob rather than tossing in Goring Blade or Royal Authority.

At the end of the day, when you and two others sit in DF for a while waiting on a tank, just remember that even the decent or good tanks would rather do other things.
