Guild Building/Improvement/Leveling

[Cavoc]

I'm not sure if this has been talked about in the past, but i'd like to get it out there.

Would it be possible for guilds to level up with the characters in the guilds?
For guilds to be based on a leveling system, and the more as each character gets xp, the xp will go to the guild level as well.

Leveling system:
For example: A Level 1 guild has 0/10000 xp. Each time a person in the guild receives xp, the guild will too.
Full guild runs together could even possibly give bonus xp. (if the game is full with everyone in the same guild).
This will build the guild's people together, make it more active, (We've all been in those guilds where absolutely nobody talks) and have the
guild act as a unit as it should.
As for level 76's (or whatever the level cap may be) who do not earn xp, they could help out other guildmates of lower levels.

Achievements:
This could also result in more achievements.
For example: an achievement for reaching Level 5/Level 10, etc.

Vanities:
A guild vanity.
This would make people want to level a guild up.
For example: Every 10 levels is a different vanity. (Sorta like the veteran's one, where they come separate, but all piece together.)
Shields could be creative. There could be 4. One saying Member, Recruiter, Officer, Leader. (Each shield getting a little cooler as it goes up.)
As for the leader, he could get a crown, or custom vanities of his own.(This could promote people to buy guilds themselves $$$)

This could possibly be for any STS game, but I play pl.
This could need many adjustments (if even possible in the first place), but i just wanted to get the idea out there.
