What is a "bad player" to you?

[Keizerwilson]

Unfortunately this kind of mind set have been spread so badly even newbies are following, they think they must dps at all contents
I have been dying a few time because the healer (with sprout icon) think they must dps. To a point I was kill by some low level content like Ravana

Or you could try using cooldowns? Also, every tank has an invuln skill at 50.
