There are many area's in which the raid can improve so that we can move faster through the instance.
1. If you are a rezzer and somebody is dead in your party, rez them.
2. Whisper a member of the class you need buffs from and request it that way.
3. Don't expect full buffs for trash.
4. Drink for mana in shorter bursts.
5. Blow 3 to 10 minute cooldowns on trash (spells, trinkets, equipment uses and potions), save 30/60 minute c/d for bosses.
6. Bring plenty of your own reagants to the raid (potions, temp enchants, candles, symbols etc).
7. Be aware of your surroundings, if you see a dangerous add coming to you, move yourself and don't expect to be told to move.
8. Know your toon, don't expect others to tell you how to play it. No reason somebody should be telling hunters to FD every time its up or that rogues should be vanishing or Feinting.
9. If you are new to the raid and don't understand the short version of the boss strategies, ask somebody of your class what to do.
10. Use the addon package I have put together...it has the base essentials that every raider should have to help make things go smoother.
