id actually like to see an applicable use for badges in your legion base,
100 blue badge to put a truce effect on the defending base for 30 minutes - 1 hour
100 red badges to increase attack output of base by 30% for 1 hour
50 yellow badges to prevent your base from being raided << through that in there because I like to spite people, its fun

^^ I made these up off the top of my head, but you get the idea. It would just be nice if the badge system were more versatile than simply buying artifacts, might breath a new breath of life into pvp.
heck : 10 green badges = 1 time use arti for free planet invade.
