As of right now there are only 2 real basic features of guilds: Towering and Guild spar. So why not expand or create new things for guilds to do and incourage co-op play in the process? And maybe use it as away to alter the reward system.

1.Missions There are several bigger basically ignored seldom used buildings around the map in the different areas like the arena in snow,Mcormics in Belle island,ect. Why not convert them into places where you and your guild mates can battle boss baddies? My thinking is if you die rather than respawning you have to sit outside the area and observe like you would in spars,and if your guild defeats the baddie you still get the spoils or reward.

2.Guild team events These are just the common events we all ready have that are elimination style co-ops. Like freeze tag and team fort. They could put those in the seldom used buildings as well and made so guilds can vs each other and win spoils as well as points for the guild. Guild spar would fall under this catagory as well.

3.points system This has been discussed before. This is how i would work it.

You get rewarded points for:

1. taking towers,
2. for each hour you accumulate holding the tower.
3. you would get x2 points for taking multiple towers.
4. winning a G-S match
5. defeating a boss baddie and completing a "mission".
6. winning guild team events.
7. they could reward guilds points for members winning individual events as well.

They would obviously need to add more stat colums for these things.

There would be a running talley of all points earned by guilds. With ranking lists of the highest point scoring guilds in total points and for each individual guild task or competition won or completed. Then after each month or season rewards would be handed out to the guilds with the most points in each category.
