how hard is it to do the simple things?

[DoubleT]

When I started playing, I had no idea about swiftcast until I was cursed out. How was I suppose to know? Simply explaining about swiftcast would have worked instead of being rude.
So Garlyle is right. Don't assume. Try to explain while being calm. If they don't want to hear you out, let them continue to be fail. Maybe they will learn.

If you was a new player an didnt know then yes that is understandable. If you are lv 50 an in Titan HM (as garlyle stated), an still havent figured out about swiftcast, then ya, you are gimping your group. You will never be able to raise anyone in that fight no matter how hard u try, so you shouldve figured it out by then, as i highly doubt you never encountered difficulty with the cast time at anytime befor then.
