I don't watch videos or read guides for normal dungeons/raids. I like going as a healer for new content, since I can cover my butt if I screw something up (unless I got one shot), then hopefully remember the mechanic in the future.

For specific fights, I try to come up with an easier way to remember - for example, red (sohm al nm 2nd boss) or dragon (chimera) is for hugs (stack/close to boss), blue or ram is run away from the emo kid. :v Some fights, I'm just hopeless for - stupid fore/aft/port/star gets me every time. Practice makes perfect.
