This is actually a pet peeve of mine. Just a reminder, it is BOTH the buffers'/buffee's responsibility to ensure that everyone is buffed. Waiting until people say something before rebuffing them causes unnecessary delays and last-minute mana regen.
Tips for buffing classes:
* Watch your CT Raid buff timers. I mouse-over the entire raid's buffs before every boss fight to make sure that all buffs have more than 10mins remaining....if not, I rebuff.
* Organise buffing with the others in the raid. There's no need for one priest/mage/druid to be buffing the entire raid normally. Coordinating buffs ("I'll take odd groups, you take evens", for example) saves time and lessens the burden on any one player to fund the reagents.
* BRING REAGENTS! I can't stress this enough. I don't know about priests, but for druids and mages, I suggest at least one reagent per member of the raid. So, in essence, that's 40 arcane powder/thornroot per MC run. You'll likely not even go through half of that if you coordinate, but it's always good to come prepared. Also, for shaman, I suggest at least one ankh per cooldown cycle for the duration of the raid, if not more. You never know when you'll be the one who's in the best spot to pop...or who will run out. Help the raid, yourself, and your fellow shaman out by bringing extras and being prepared.
* Rebuff the dead IMMEDIATELY. Don't make them ask, because they'll frequently do so during combat, when you can't drink or don't have the mana.
For the buff recipients:
* Be patient. Buffing classes have alot of demands put on them and buffing often takes a crapload of mana just to cast on one group. You won't get buffs faster by saying "Oh, I need a paw/AB/fort/spirit/shadow protection too" than we have mana to cast. If the buffing classes heed the advice above, you should rarely need to ask anyway.
* Try not to be the "me too" person. If you see two or three groups individually asking for buffs, take charge and see if you can't help the buffers out by seeing which groups need buffs. Seeing someone say "groups 1,4,5,8 need fort" is much easier to handle than seeing four individual "group x needs fort" messages (or 20 "I need a fort" messages).
* If you need a single-target buff, please use raidchat or whispers. Entirely too much of TS is tied up in "I need a fort/paw" when it could all be handled with a tiny bit of typing.
* Sometimes, take notice and learn to live without. If you have a single druid in the raid, for instance, you may find that getting a mark is tough. See the first tip on patience, but also bear in mind that one person can only do so much...and you may have to enter combat without the buff a few times. Honestly, it's rare that any one of our buffs makes "the difference" and I've gone through many boss fights without at least one of the usual buffs up...it's not that big of a deal. Feel free to click "no" on a ready check for these cases, but trash mobs are hardly worth stopping the show because a person or two hasn't been fully raid buffed.
* Before asking for a buff, be sure you are unstealthed and in-range. I've had stealthed rogues ask for a fort that were literally five rooms away...buffing has a max range, folks, and stealthed rogues/druids do not always get buffs. Many of us do know the mechanics of buffing and there are some tricky elements regarding stealth (sometimes you'll get buffs, sometimes you won't when stealthed)...so please just eliminate the guesswork and unstealth for a moment (this includes hunter pets).
This is probably the wrong thread to do this in, but I just had to post these again. Let me tell you, it SUCKS playing a buffing class, so have some heart, folks....we're often doing the best we can. If you think or notice someone that isn't pulling their weight buff-wise, though, please point it out to the raid leader. I've blown through more arcane powder in some 20-man raids than I do in MC because of some slacking/unprepared mages...I don't want to see that happen to others if it can be helped.
Last tip...if you're PvP flagged, do everyone a favour and do not zone in at all until it drops. PvP flags are infectious and inevitably will spread. Totems and buffs do discriminate between flagged and unflagged, so mix-and-match flagged/unflagged does not work for raids unless it's part of a strategy. When the time comes for BWL, you will be kicked from the raid until your flag drops to prevent excessive delay...word of warning, so be responsible please.
