I haven't particularly had reason to use future tense. Generally I word things in past or present tense, but the action itself has no actual conclusion or consequence attached to allow the other party or parties to respond, especially in free-form fight scenes.
e.g. "He swings/swung his sword in a wide sweep." "With a crash he leapt towards the banquet table." "He slipped a white powder into the punch, hoping he wasn't seen."
I can't think of any contexts in which anything else would be simpler to use, and I don't feel any particular need to control the other party's response in any circumstance.
