I get it. People wanted to check the new DLC, all joined Azuras (how typical), saw the queue over 100 and QQed on the forums. That's why you opened 3 more campaigns.It was a good move for then.
But now its been over a month. Everyone had his fair share on IC, collected some TV stones, got their willpower / agility jewellery / whatever else and then bailed, of course, because you already announced the next DLC..
What's left behind though?
With what I've seen in EU, its mostly 1 alliance with strong roster and the other 2 semi dead / completely dead.. Each campaign has its own zerg that's just owning the whole map.. So much for campaign balance.
Just close minimum 2 of the 30 day campaigns, give everyone their rewards based on the leaderboard (not that the rewards are worth anything...) and maybe then we can see some alliance balance back to Cyrodiil / an alternative to Azura (which as a campaign is "fine", if you don't mind the lag).
