This is a very good question. You will be surprised, towering has more problems than any other activities on Graal. I would say towering and sparring is the major part of Graal and it's at failure at providing the best.

The problem for towering is, it sort of works like social hierarchy. All the major powers belongs to the leader. It's not fair, only the survival of the fittest survive.

All the other major flaws are similar to this. I have faced these problems exactly a year ago and I couldn't come up with a solution for this. That's the reason I quit helping towers, because I grew up in the individual society and I can't understand this.
