I have an idea for a guild wars event. This event would not only be challenging but be fun. It's similar to the hunger games but different.
What would happen is when ever the staff wants to run the event they would post on the forums a week before the event saying it's a certain day and time, and for all guilds to apply with a post to be able to participate in the event. then once the staff has all the guilds that want to join in they will make a gate to a area with a little area for each guild, like a room or something. In this room 1 team mate will always stay and that will be the guilds crafter, now the crafter will make the armor and weapons for the whole guild. You can either start each guild's crafter out with a box of ingots and crafting supplies, or make them have to mine it all up and smith everything. the fighters once their geared up n ready to go will all enter into the arena by a portal, but the thing is that other teams may enter the portal of the other guilds. This will make it very tricky because then other guilds can cut off their source of gear and items they can get. So not only do the fighters have to stay alive they have to also keep their crafter alive during the event. like i said this is similar to the hunger games, but differ's as it takes more team work to keep your crafter alive during the fighting that's going on in the arena. Also there will be no mounts so basically the team has to stick together through out the whole event. The way to win the event is by killing every other guild fighter and their crafter.
Personally I think this would do alot for the on going drama between guilds as they would have a chance to settle it basically on a battle field and get their frustration out that they have pent up inside, and also seeing which guild works the best together as a team.
