Change: Event based regeneration for moves/mana/hps

This sounds like a significant and possibly quite interesting change - and it will get away from the slightly unnatural experience with other MUDs where player's get to time some things to happen before or after a TICK. One minor issue might be if the player base gets too big in that one timer based modification to the players' stats every minute takes less CPU effort than one every second, and if it is something that is being reported back to the players by an out-of-band protocol will increase the bandwidth needed. You may find that you have to compromise to, say, updates every 5 seconds.
