Utopia (http://wow.curse.com/downloads/wow-addons/details/utopia.aspx)
This addon might be useful for RL to se how do we manage to keep up buffs on ourselves and debuff on bosses. It groups the non-stacking type of buffs and debuff for better visibility. My opinion is that we dont get as much as we could get from debuffs as it seems some classes are not communicating with each other (or within themselves) as what buffs and debuffs would they bring.
As an example IÃ,´d pick up warriors and their sunder armor. If we have warrior tank on the boss, it is fine. If we only have DPS warriors, it is almost granted that there is not going to be any Sunder Armor (or Expose Armor for that matter). I know it is a DPS loss for the one who is doing it but the loss is outweighted several times by DPS increase of others benefiting from the debuff.
It might help us here and there
Also, I am sure you know about this tool but still, here goes the link:
mmo-champion raid comp (http://raidcomp.mmo-champion.com/)
I used to use this, but I got fed up with slow updates and the resulting WoW errors post patch. Excellent idea though.
Seems to have been updated last month for 3.3.3.
Screenshots and info looks good, I'll give it a trial in one of our 10mans.
