But they never do. They only dogpile the smaller side (usually knits), until it's in the corner, has no radar, no ords at any field, nonstop attackers over its HQ and strats....
And the map never resets. It doesn't work properly. The rules need changing. Once I figured that both bish and rooks had about 42-45% of knit fields, but none of each others. We were in the pocket with a handful left and being reamed from both hordes at once.
It needs changing so that this either 1) is discouraged or 2) triggers some new rule to do something else -- i.e. reset despite both other teams not taking each others' fields (or whatever-rule-you-might-suggest)
