There's no reason to try hard in dungeons. Telling people that they HAVE to go 100% in dungeon runs is a quick way to scare them away from Scholar, like you almost did to ZadocFish. Dungeons are the opportunity to learn your class, make mistakes, and experiment with new things in a live situation. I've recently re-optimized my hotbars in order to make controlling Eos in CS easier, for example. While I was working the kinks out of it I went as hard as I could in the dungeons, properly keeping up my cooldowns, micro-managing the fairy, and contributing significantly to group DPS.

But if I didn't? Nothing would have really changed. The dungeon would have taken maybe two minutes longer to complete. End of story.
So I'm sorry if my 50th trip through Antitower is a "lazy", but to be quite frank I just don't care.

Like I said, a well-geared Scholar doesn't need to contribute ANYTHING to clear dungeons. Eos is enough, and sometimes so is Selene.
My point here is that it's your choice to DPS in dungeons. Most tanks I run into don't use cooldowns. Most DPS I run into don't know their AoE rotation. Why should I be forced to try 10x harder than everyone else because some guy called me a "boiled lala"
Raid is the only place where I would suggest that you ABSOLUTELY MUST DPS. Anything easier than that and it's optional. Lately however, I have been giving dungeons my 100% because I'm trying to rebuild my skills after a long hiatus. Keep in mind that for quite a long time Scholar's DPS was regarded as a "neat little bonus". My DPS contributions were the difference between 1 bee or 2 in T6, but certainly not the end-of-the-world if I didn't participate. As such, I never really mastered my rotation, I just sort of applied DoTs and then sort of forgot about them afterwards when I went back to healing. It is an extremely recent trend that people have started to care about just how much DPS you're able to parse, and so I've been giving it my all to finally learn my rotation and push myself to the limit.

Once I'm there though I'll probably start slacking off again. At the very least late in the week when I'm tired of roulettes.
