Keep current system but add things to it

How about organizing a weekly guild pvp tournament? Participants are the top 32 guilds. Randomly divide them into 2 brackets, and have them fight it out until the finals. Based on their rank in the tournament they get a bonus points.

EXAMPLE:

My guild has 10,000,000 points on guild LB. We get 1st in pvp tournament. Lets say at first place your guild gets 50% increase in points. Now my guild would have 15,000,000 on guild LB after tourney

You could have this be Honor gear OR you could have two tourneys one with honor gear and one with normal gear.

You could have matches happen once ever day, since you only need to win 4 matches to reach the finals (32>16>8>4>2>1)
