All of the things they have told us about wont really fix the issue of 3.0 vs 4.0 rotations. The point at which the 4.0 rotation surpasses the 3.0 is raw PPS assuming 0 random procs, is when your Fire 4s take 2.25s to cast. And the only reason for this is because at this speed, you start clipping your thunder dot by 2 ticks. Having them take .2s less at the start does help reach this, but that doesn't fix the problem. Now if you introduce T3P, which highly benefit the 3.0 rotations flexibility, you still don't have solid reason to do 4.0. They need to make UH do something more beneficial, or revert the potency nerf. But who knows, maybe there is more that we don't know. We will just have to wait. MP management will most likely not benefit 4.0 outside of making the rotation more reliable, not potent.
