Interesting idea, yet I believe the devs are missing the mark. Lots of people seem to think there were huge differences in bfe during s1, but thats rubbish. Most people hadnt warred long enough to have full sets of mith gear to create a huge variance. There were less towers across the board. Top clans had 2m sdt and it was the exception, not the rule, on people having adt. It was during tbat season that rh began exploiting the big/gh to their advantage. In todays world, 10 30M cs and 10 1.5m cs builds will still destroy a balanced clan with 20 16m cs members. Always have, always will. Bigs skim/ko the mids while the sh dump spies to sko and plunder on the mids out of ko. Mids cant hit the bigs and the sh pay them nothing. I dont see how taking bfa/bfe out will fix this.
The mix of the clan roster is way more important to determining a fair match then the total strength of the rosters. Ive repeated this so many times to deaf ears, but until the devs implement statistical measures (standard deviation and variance of the rosters, plus range from high to low), then matches will suffer and unbalanced rosters will rule ee and mids will continue to be excluded. Or to a lesser degree, as fonzi mentioned, tiers for different sizes. This wont eliminate the unbalanced rosters, but at least it'll reduce the variance.
I plan to give this new system a try, but I believe mids will still be a dying breed in clan ee wars once the fad wears off and the balanced new clans get stomped on by the big/smalls. At least the mids can still do indi wars which are fair and balanced in our range. Although Ive heard the big/sh brackets are a crap shoot.
At least I can keep beating the dead horse while the devs pretend to listen.
