Why are low standards for dps acceptable?

[Iagainsti]

If you dont understand your abilities why on earth are you doing content at level 60? Knowing what something does is the first thing you should do when unlocking a skill and if you don't understand your abilities and refuse to find out what they do you are indeed either lazy or incredibly rude to the other people you get stuck with.

That is a question posed for those players, as I do not have that answer. I agree with you that players should know the class they are playing by level 60, but you, and quite a few people here, are disregarding human nature. Just because you can reason properly and are conscious enough to comprehend, doesn't mean that another person doesn't need instructions on their bottle of shampoo.
