I think the real problem is that if one player hates complex combat, and "opts out" of all of the combat tactics, but the rest of the group "opts in", then that player still has to sit there for twenty minutes while the table goes around deciding all of the tactics of the battle, while he basically contributes nothing to the interesting discussion at hand and just swings his sword.
One way to handle that would be to handle the "slow deciding" players slightly differently. Instead of all or nothing, which tends to not get enforced because of that "nothing" part, go with reduced effect for delays. That is, instead of, "take too long, you delay this round," have something like -1 to hit and damange for every 20 seconds spent past the first.
Breadth instead of depth of complexity would dovetail with that, as well. The guy that likes complexity wants to pick the level of complexity that satisfies his desire to have options, but not so much that he can't decide quickly and get one with it. Otherwise, he loses effectiveness.
For a more positive presentation of the same idea, present it as a nice bonus to hit and damage for those that act quickly, which you progressively lose pieces of as you delay.
