Offer advice before you take to a public forum to complain.

Yet- Some people don't take advice well. I was trying to help a SCH out ( I have a SCH on a different server and it is my first main class since open beta) She kept spamming succor and wanting me to play mage ballad. After I politely offered her some advice and showed her aetherflow (By the way, she was lvl 50) She got mad and said "Well you don't have a healer so what do you know." then we all died.
