I'm very late to the party and just read galvuus theory crafting on 3.0 vs 4.0 rotation and wow that is such an eye opener! I love the ease of using the 3.0 rotation and it is good to know that that is our highest DPS rotation.

I don't have any qualms with b4 not being part of single target at all in fact I would prefer it if it was only useful for aoe double flares. the 3.0 rotation is much easier and that helps with all the movement were gonna be doing in deltascape 3 and 4!
