I think a full clan league would be really great. However, I think instead of all-kill, a Proleague format (both in terms of match and league format) would be better. It rewards teams with depth and more people get to play.
I'm also extremely curious as to how the Frogmite format is intended to work! Mainly because while there are clans that tend to focus on one end or the other, there are also clans like TA which seem to span the entire spectrum.
