I have been warring in EE for a long time, some know me, some don't. Mathematically, the reason big lbers with ghs work is because they never face each other. Balanced war clans get screwed by your farce of a hit ratio matching system. A balanced war clan with a sprinkle of 16-18m cs, some 10-14m cs, and a few 4-8m cs members will have a near 100% hit ratio to a lb stacked / gh clan. Sure the overall CS will be equal, sure everyone can technically hit each other, but no one in their right mind thinks a 10m cs attk build will land hits on a top 100 lber with 3m static attack towers and 10T in bfa. These lb stacked rosters rarely face each other because they run a 40/60 ratio of builds that cant hit top to bottom. They will always fall below the 75% hit ratio.
How do you fix this? You change the matchup algorithm. Hit ratio is a joke. A 3m cs towered gh can hit 20m cs+. Manipulate that same gh to 1.5m cs and he hits 8-9m cs max. Mix in some 20m cs with bfa builds, throw in some 1.5m cs ghs and you have a hit ratio manipulating roster that will only draw balanced rosters. No wonder all clans are going to the same roster. Easy enough. The matching tweak has to be done using easily implemented statistics. Total relative strength is already built in. Add in total range of builds, 20m cs max, 2m cs min = range of 18m cs. Add in standard deviation and variance metrics. A top/bottom heavy roster will have huge standard deviation/variance/range metrics and will be matched with similiar size and built clans. Balanced clans will have smaller standard deviation, variance, range metrics and will be matched with similiar built rosters. This would greatly reduce the roster manipulation done by lb/gh clans. Now they can fight themselves - KaW rejoices.
Until the devs seriously take a look at statistical measures of roster development, these lb/gh clans will continue to exclude mid-sized warriors and hansel builds. If the devs need a crash course in statistics, drop me a line.
