Personally I start Bloodbath a good 7-8seconds before hand but then I combo 1.)Bloodbath(now 22-ish sec), 2.)Internal Release, 3.) Berserk 4.)Maim, 5.) Unchained.

The damage return from the hp of the buffed Bloodbath by Berserk and Maim and Crits from Internal Release. Unless I'm tanking Titan, healers rarely have to heal me during this time. As always (until patch time) use infuriate after popping unchained to keep your healing bonus.
