If it helps out, you can turn off a lot of the visual clutter in options. I've adjusted this since Delebrum Reginae was current content, and can't really live without it as dodging became much, MUCH easier. On the flip side, this has made dragging people kicking and screaming over the finish line for me the norm.
If you are having trouble with mechanics, you are more than welcome to ask about them. More than likely someone else who is more familiar with the fight will mark themselves as the Danger Dorito and move to the safe spots for you to follow. Couple this with removing the visual clutter from the Options and you can make a lot of the fights that much easier to do. Speaking up and asking about mechanics is VERY MUCH ENCOURAGED and the rest of us will be far more understanding for it.
Mechanics are not hard. However throwing yourself like the RDM I had was doing in the fights because they decided laying on the floor and timing out my raises for two whole minutes each in their tantrum was a much better option makes things MUCH harder for the rest of the group, like the damage-heavy stacks and dps checks.
If it comes down to it, stop dpsing and do the mechanic. It is much easier for a healer like myself to patch up raidwide damage over dumping another 2400 mp on scraping someone off the ground.
