Agreed with Wiggles. There'd be a lot of coding, and a lot of potential issues/exploits/griefing cropping up if FATE's scaled based on the number of players that joined in. Especially if you want them to scale on the fly as players join/leave the fate "zone" as it were. If it didn't scale as players join/leave, there could be easy exploits by having one player hit the FATE, mobs pop up based on 1 player in the FATE, 30+ people jump in to try and get credit, can't, now just wasted their time while the initial player reaps all the rewards for just being there. The other alternative is if FATE groups are roaming around, the opposite happens. 30+ players roaming the countryside looking to isolate players, as a FATE pops up, mobs spawn for 30+ players, those same 30+ leave the one player to fend for himself, likely getting killed in the process, thus griefing.
