I think that Sardon's Tower is the poorest excuse for a guild fort that we have. This can be attributed to the fact that it was never intended to be a guild fort area. Sardon's Tower has always housed a quest, and the levels that are used in the tower are from this quest. I don't think it could be edited in a way that would make it a suitable guild fort either without really changing its structure entirely. If we were going to do that it may as well be reverted back to its original quest form and a tower could go elsewhere. That's just my personal opinion though, it will probably stay as it is.
