Heroic Beasts, 25 Man

That being said, have you had any extended P3 attempts? Warlocks tend to run into mana issues, and lifetapping requires additional healer attention/coordination. As such, it's generally best for warlocks to go demo simply because it gives you the best mana longevity. Given you only have one warlock, though, it may be possible for him to do whatever he wishes and have a personal healer.

You lifetap before phase 3 begins or just as it starts to get you down to where you should be healthwise. If your Warlocks are holding onto their health before phaes 3 begins or shortly thereafter, they're doing something wrong. You life tap down to 35% to 40% just as phase 3 begins, then you use Life Tap 1 to maintain the life tap glyph buff and shouldn't be in harms way and should have enough mana to finish out the fight.

And also, Demo *is* the way to go. The DP buff should never be down and a properly geared Demo Warlock is going to be looking at 4k+ SP (I'm around 4.4k full raid buffed, my IotDS fully charge through pre-fight LT1s, and Life Tap glyph up). This beats getting the 280 SP from Flametongue Totem by far. Just make sure that you stand as close as possible to the middle of the raid as you can get so that all spell casters get the DP buff. Also to add further to this, DP is typically up 90% of the time or more, this means that a Demo Warlock should be looking at giving all spell casters about 360 to 400 more SP at all times (80 to 120 more SP than Flametoungue) which equates to roughly a 120 to 180 DPS boost for each offensive spell caster in the raid (this is more an avearge as some spellcasters get more of a DPS per point of spell powers than others depending on their specs) so you're looking at a RDPS in of 120 to 180 x # of offensive spell casters (usually this equates to around 600 to 900 more Raid DPS for 5 offensive spell casters, not sure what kind of HPS this allots to with healers).
