I don't get on the board much over the weekend, I check it out during work lol.
I was thinking. If you get an awesome reward, maybe it can benefit the entire guild somehow.
I'll explain. Say one of the rewards allows you to use gear you've already collected to build or create something. It could be like a trophy. Say it takes x amount of furnaces, y amount of bacta gel canisters, and you can create a bacta tank for the guild. It would be setup like a trophy though, so no real implementation, but the benefits of it would allow a certain percentage of heal over time during arena battles. Maybe it would allow you to have a 6th battle in a raid.
Another trophy could be Han Solo in carbonite, so on and so forth.
The kicker to the trophy is, its power depletes with time and you would need to sink resources into it to keep it going, or let it go and get a different trophy. This would be a perfect way to use the gear us upper level guys have no need for, plus it would allow guilds to be "modded" so to speak and give an edge.
