From a play balance perspective, SE4 style turn based combat is fundamentally broken. Real time execution eliminates the absurdity of one side firing all of its weapons before the other can react that plagued SE4 to no end. SE4 combats tend to be very one-sided, with the victor barely taking a scratch. Some mods can ameliorate this somewhat (aka leaky defenses), but the intrinsic flaw remains.

It is certainly possible to make turn based combat systems that emulate the realism and inherent balance of real time execution, but such systems tend to become bogged down with needlessly complicated initiative and phase rulesets.
