The only way I think that would make towering more interesting is making it so that guilds can only have like 8-10members in. Would make guilds have less at each tower and guilds less likely to noob recruit as perms wouldn't like being kicked all the time. It would be more challenging and give all guilds more of a chance as towers would be changing over ownership more often and guilds wouldnt be likely to hog 2+ towers at a time for several hrs (cause' guild holding low members -Not likely to stay online forever) It may even make players want to start making these 'pro linkup guilds' like what seems to happen for gst for some guilds.
