It doesn't matter what your Attack
efense ratios are; initiative-less combat is a terrible, terrible thing in any case. You can partially ameliorate the other absurdities with very high defense compared to attack, but it doesn't change the inherent flaws in the type of combat engine SE4 uses. Having all of the objects owned by one side arbitrarily move and act before all of the objects owned by the other side, every turn, is just bad game design.
