Tiny bits of advice from someone who's gotten some "Vashj" before (and believe me, it didn't feel very sexy):
- Keep TS clear unless you're performing a specific role: keeping watch for Tainted Elementals, announcing spawns (keep it simple, ie: "Strider North!" or "Tainted Southwest!"), alerting close-by players that you have a Tainted Core, etc. There's going to be a metric crapton of spam throughout the fight due to macros, so make the most of those ears!
- Keep at least 3 to 4 inventory spots open. Tainted Core icons look very similar to Healthstones or Netherwing Eggs, so don't waste time rifling through bags for em: target someone close by, and use the macro!
- For Phase 1, I suggest we paladins set up a Blessing of Freedom rotation on Cal. The longer he's stuck in place, the more damage we suffer from Multishots. In my last raid, we had the MT simply shout "freedom!" over TS if it became rooted in place, and the pallies would take turns setting him free. Free Action Potions are helpful too, but not recommended in case the tank needs to take a swig from health pots...that, and it will not remove the snare if the tank is already affected.
- You can pally bubble/Ice Block out of Static Charge. Be quick if you decide to do this, so you don't mistakenly zap your nearby friends.
- Phase 2 is one icky NPC zergfest. Zoom your camera out as far as possible so you can see your allies & important spawns. The more action on a platform you can see, the better. I personally use Improved Camera 2 to increase the zoom threshold without mucking with WoW's configuration too much, and I have a nice view of nearly the entire platform.
- A mage can Blink if it is holding a Tainted Core, but cannot make themselves immune to the Core's "snare" side-effect. Beware of this tactic though: make sure the path ahead of you is clear so you don't bump into a Strider or Naga cleave, and don't Blink too far away from a player that is close to a pillar.
- Spore Bats in Phase 3 can be killed by ranged classes, but we can only spend about 3 or 4 minutes taking them down before they become too numerous. After those first minutes, they spawn like rabbits, and it's imperative to unload upon Vashj before we get stuck in a sea of Spore Bat poop.
- In the event that something goes horribly wrong: die safely, and die swiftly. Make a dash for the west end of the platform and wait for death (not everyone can avoid this, but it's worth reminding people), so we can pop and rez quickly while we discuss tactics. Don't be brave and make a dash for the bridge. Vashj will chase you anywhere in SSC, including to the Elevator Monster.
- Turn on Free For All loot thresholds so we can interact with Tainted Elementals/Cores, but do NOT accidentally click Vashj's corpse when we down her. If someone is suspected of having butterfingers, quickly turn Master Looter back on during Phase 3 (if it can be helped).
Last time I edit this. No. Really. I think I covered all the bases. I'm gonna go back to work now
