Communication piece

Communication in a raid is vital. It can use the eyes, or it can use the ears. It's very easy to decide that eyes < ears in terms of raid.

• Ears don't require typing and reading. Everybody keep their eyes on what's important.
• Speaking is faster than typing, so more information can flow in the same period of time.

But! Shifting perspective.

• Everybody keep their eyes on what's important — if there's something they are needed to be specifically told about, they are not, obviously.
• More information in the same period of time equals, yes, yes, you guessed it: SPAM.

So what do we have here.

If someone needs to speak, it is most likely a warning before a mistake. If someone's screaming for Innervate, then someone else failed watching raid frames. If one tank has to tell the other one to taunt the boss off, then other tank failed to set focus target with debuffs and set up raid-warning addon (that's failing twice).

While backing each other up is all nice and good, when almost every mistake there is to be made has to be voiced, it's too forgiving. People think that meddling with UI isn't worthwhile, they'll hear everything there is to know. UI became clogged long ago, but now there isn't an incentive to do anything about it. Four Horsemen of Apocalypse ride among the heaps of virtual corpses and bones, because once your raid leader made you install TeamSpeak.

Voice communication can help to turn those without hope into a decent raid, but it cannot turn a decent raid into top-progress monsters. It's almost like crutches: if you have trouble standing, they'll help, but if you are a professional runner, they can bring more trouble than good.
