I think you can drop diversion for addle. Using lucid when threats are nearly at max worked fine (at least for me though).

But I agree it's clunky with requiring to be in UI thing. The only situation that doesn't incur dps loss for BLM to use mana shift is that you have thunder proc ready and Blizz 3 > Blizz 4 > Thunder proc + Shift > Foul, which is not that uncommon but troublesome to use XD.
