This video is entitled "Pull! A Guide to Faster Raids," and it's been produced by Kyth, of Fusion (US-Turalyon H). Set to the backdrop of (part of) a Naxxramas speed run, the video presents some easy tips for raiding faster. It's mostly addressed towards raid leaders, but I certainly plan on bringing some of the concepts here forward in my next raid. You should watch the video - it's well made and fun - but here are some bullet points I've taken away from it:
- Pull fast. Have impatient pullers, have your plate DPS off-tank trash if need be, and don't wait for rebuffs if one or two people die (just do it on the fly).
- Loot fast. Whether you use /roll, DKP, or loot council, make someone in charge of it, and do it fast.
- Set high expectations. Initially, your raiders might have difficulty keeping up with an increased pace if they're not used to it, but within a night or two they'll get used to keeping moving all the time, and you'll have more fun because you won't be standing around constantly.
The last point above brings up an important issue: fun is essential. For most guilds, it's why we raid. Pushing your raiders to play at a better level shouldn't suck the fun out of raids, it doesn't mean you can't joke in vent; it means there's less of what we don't like in raids: waiting while people are AFK, endless ready checks before bosses, and so forth.
Part two of the video is embedded below (and part one above), or you can download the whole thing in high quality from Warcraft Movies (recommended). There's also a web page associated with the video, including links for recommended addons, more tips, a WWS for the speed run, and so on.
