Maybe it's so they interact with items or powers that trigger when a monster recharges a power. I wondered the same thing.
Only reason I have been able to think of as well.
I cannot think of any PC related powers that interact with monsters that have recharge powers at all.
Yeah- I think it's just a matter of why add a new* keyword to the mix when you already have something that can serve the same function?
* I know reliable isn't really a NEW keyword but it would be new for monsters.
Except some monsters do have reliable powers, and it IS defined in the "interpretation section" of the MM3 - 16 of them as per the conpendium, with about 1/2 of them from MM2 (and none from MM3, that I could see).
