BT is going to be roughly 1k-1.5k higher than LI on a pure single target fight, and currently, you are going to want to avoid SotF for single target. With improved rake and glyph of Savage Roar, Incarnation is better than SotF and FoN by a hefty margin. SotF is OK for multi-target sustained, but Incarnation is still better because of multi-dot burst with improved rake-tabbing.
Now, as soon as a second target is added that will live for an extended period of time, LI becomes better than BT, but when you have 5+ targets, BT is better again.
