If you're level 100 and you can't handle a little mid-game content, then I have news for you: just do it in 10 levels next expansion. That's what my friend does with the EX trials and Savage raids when he wants glam or mount or whatever, he just wait until he has at least 10 levels over the content and has out-geared it so it's trivial.

Either that or properly learn how to play the game. Doing something incorrectly for x number of years doesn't make it correct.
