Well then I'd say stick to one solo event ladder, but that's my opinion.
Or just have two separate ladders and lower the gold winnings for each of them.
EDIT: And yes, like acyroma said, obviously a clan event ladder wouldn't work with no other clans.
But just the fact that there are so little clans makes what I'm saying seem to make even more sense.
The one and only event ladder we have shouldnt have anything to do with clans if there are so few clans at the moment.
