This is an alternative to DD (to increase the chances of finding valuable control spells), not a buff for logistics. In theory, it could be implemented so that MP regeneration doesn't take into account bonuses from logistics specialists; then, in principle, it would be evenly distributed.

And Kirr will be running around with 5000 MP. If something like this is to be done, the MP regeneration should be the same for everyone, regardless of the initial amount.

But, in my humble opinion, the feasibility of introducing a new control spell is highly questionable. And if the idea of MP regeneration is still somewhat acceptable, then suggestions like a spell to transfer creatures from one hero to another are beyond the pale. There are already enough control spells, and they are not that difficult to find; why make the game even more dependent on control? To balance the schools of magic? And why does anyone think they should be balanced?
