- ALWAYS BE PREPARED
Additionally, know the fights and what you will be working on. Watch the movies, know the encounter. While each progressive night is a learning experience, it will always be to your benefit to not go in blind. If you are unaware of certain nuances of a fight that may be particular to your guild, ask questions from a more experienced person. Do it in class/role channels, do it in tells, even in Vent if necessary, but ask questions so you are not called out for something you should already know. Which leads me to...
- COMMUNICATE COMMUNICATE COMMUNICATE
But I stress that good communication does not cease with the encounter. The number one offense no raider can get away with is AFKing without informing an officer. By doing so, you not only potentially waste your own time by any ill-consequence of your ninja'd AFK, but the time of 24 other players. If it is an non-life threatening emergency, make a brief announcement, and tend to it; if it is a true emergency, hearth out while informing an officer. And there is no excuse for the lack of hearthing - it is ONE click. Before an encounter, everything is better communicated in chat as opposed to vent, as the officers have record of such things as AFKs and questions asked. During an encounter, Vent is best to make sure points get across, since your hands should be too busy dealing with your spells to type. But that said....
- VENT IS NOT YOUR PLAYGROUND
If you are not leading the raid, you have no reason to talk casually in Vent during the encounter. When you die, people will notice it - you do not have to say "Oh, shit" or "Fuck me" to make it known. You died, probably stupidly, okay, that's fine. And guess what? Instead of making unnecessary noise over Vent, potentially disrupting the communications of the DR rotation, you could have typed that in raid chat instead. Now that you are dead, you have plenty of time to type! Unnecessary sound bites are one of the greatest culprits of Vent clutter. Nothing useful comes from random expletives shouted over Vent. You can curse all you want in the comfort of your own home - why do you feel it necessary to push down your PTT key at the same time? As a raiding grunt, you should speak over Vent only if asked to, and that brings me to...
- NEVER ARGUE DURING RAIDS
- KNOW WHAT IS HAPPENING AROUND YOU
My biggest form of advice to prevent that is to set some tasks on 'automatic': Be able to do your spell rotation in your sleep, such that you don't have to maintain an eye on your cooldowns. Get used to a scanning rotation of certain aspects so you can maintain them. Debuffs still up? Good. Anybody near me that shouldn't be? Nope. Is the boss about to do an ability that I need to be aware of? In 10 seconds! How's my pet health? I would say I look at my shots and abilities about 30% of my encounter time, whereas another 15% is concerned with my pet, 20% with the boss itself, and then 35% with my immediate vicinity. Of course these attention-percentages shift depending on the encounter, but any time you notice you are focusing 100% on solely one aspect of your play, then you are doing something wrong, and it needs to be remedied. If you screw up because of it, fess up and fix it.
