3. Playstyle -
I play most classes myself, Ive had them all over 65 at least, so I have a good idea of what abilities classes have, and could reccommend a rotation for most of them.
If you have not already, go onto the Elitist Jerks website, head to their forums, your class section, pick one of the many guides and simply take/copy/adapt: a) A talent spec, b) A rotation/priority for your abilities, c) anything else you may find useful, but I wouldnt take it too far - they do a lot of complicated maths on there and talk about concepts way above most heads.
Players should be aiming to reforge hit if they arent already hit capped - as I once read on EJ and always remember "Nothing harms DPS more than attacks flat out not connecting" - what would have been a 40k crit is still zero DPS if it misses.
Other advice: Paladins might want to pick up the CLCRet addon, it basically tells you what to do. Healers should probably look at getting HealBot and Decursive addons. HealBot is basically imbalanced, especially if you have an availible interrupt like Shamans do, and Paladins will have come the next patch - it means you can heal players and target a mob to see its abilities at the same time, without having to retarget and miss something.
4. Addons -
Im not the kind of guy that makes addons compulsory, im not loaded up with them myself, my UI doesnt look like it came from a first person shooter, HOWEVER, you should well be aware of the following:
Deadly Boss Mods - Tells you when things are happening, when boss abilities are on cooldown, when to run, when the fire is coming, how long till the next phase or adds, and shouts at you when these things happen. Its like having the tactics right in front of you all the time.
Recount - I don't even know of anyone who doesn't use this tbh already, BUT it will have a very special place in my raids to start off with - the bin. Use it as a personal performance indicator by all means, but Im not in a position where Im going to be entertaining moaning about people's DPS - there will be minimum DPS requirements on all fights, and if someones DPS is exceptionally low to the point of "What the Eff" then I shall monitor it myself - so long as everyone is above the DPS requirements and such, I shant stand to hear those who might be way above it complaining about those just near it, but above it all the same etc.
TL;DR - *** Vanity Meters Off ***
5. (Last one I promise) - LOOT
Yeah, that's what we're all here for right?
Loot will simply be conducted by rolls with the raid leader as Master Looter - Priority is Main Spec/ Off Spec/ Impending Spec Change/ Disenchant/ Greed.
"What is my main spec?" - Different leaders have different systems; some day its the spec you play the most, the one you regularly raid as, the one you like best etc etc.
For the purposes of these raids, your Main Spec will be the one you are playing in the raid, notwithstanding any spec switches that may be requested for certain bosses unless you are staying in that role for the rest of the raid for some reason (i.e. the switch is permanent, or at least for a few more bosses).
Apologies for that being so long, I suppose you could take it as a lot more than an advert for a raid team!
Oh....and the team name....."Team Herb"
