While 2-3 people are actually activating the event and doing the hard work, 20 players will idle in the spawn room ready to nuke the bonus mobs. People who actually activate the event won’t get there in time to get their share of the reward.
Please make it so that only people who helped with the event are able to enter the room and kill the mobs, and also make it so that the room teleports people out of it and back to the zone entrance when the event activates, so only people who go in through the door actually get to the bonus mobs.
Additionally it would help if you took out the ability to get into the room through wall jumping.
