I dont think faster combat necesarily mean shorter combat...
I mean love encounters as well ... but truth be told there isnt much to do in between your turns, so making that part as fast as possible is certainly welcomed (swarm ai makes tremendous job in that matter) ... alternative would be to give us something to do, like u know, proper reactions.

Anyway i would see faster combat as pure benefit, the fastwr enemies will decide their turn the faster they will execute their actions ... the sooner i get back to obliterating them. :3
