The same old comps over and over are monotonous and cause many players to lose interest. It's one thing to have comps every week or weekend but not the same thing over and over. You should expand the contests to include training comps, building comps, kill events, gear enhancement, and so on. But let such events stand alone not the monarch event we have every weekend. And even more important make two versions of each. Individual and alliance events. Then give good prizes for the top finishers. Some alliance and individual contests could be ran simultaneously of course and occasionally run a series of contest back to back for a weeklong special competition. This adds interest for individuals to show their strength but also reinforces the alliance network.
