This is a fabulous idea. I really miss iwars, they were fun, short, and a great way to meet new people in the game. Even if they don't want to integrate it with a hunt, they can maybe offer iwars in between hunts for a change of pace.
The Agent Orange Wars were a lot of fun. I would kick myself when I missed sign up time. I'd love to see more Iwars. It'd really be a win for everyone. The Farmers would be distracted warring leaving the cc noobs...err people to party. Therefore ata would make the farmers happy and their party lovers happy. Just my opinion.
