I'd just like to add, since I haven't seen it here yet. You can take away character agency just as easily with future tense as with Present and Past tense. I see examples of it in some RP at the Grindstone on occasion.
Example:
Rodney would make ready to swing his axe at Steve, if the blow hit, it would sever him in two.
Using future tense in this way restricts your opponents ability to decide how a blow would hit them, and is perhaps the most annoying use of future tense I see in RP. Your tense and writing isn't what matters in RP, your intent to allow your opponent to respond freely is.
