For me, it all depends on where you set the battle. Plain flat space like a generic room or field, that's going to get boring. But set the battle in say, a library, now things get interesting. The opponents can jump to other floors via balconies, knock shelves over on each other, set books on fire (though I'd be aghast at such), and more. A good one-on-one fight (or really, any setpiece battle) should have a dynamic element that changes over its course. In the aforementioned library, maybe the fire spreads and the whole thing is on fire. Maybe the library's anti-fire magic is triggered and there's no more breathable air in the library. Maybe the security golems get activated and now both parties have to worry about those, too.
