@AmirkhanInd Thank you for coming to the forums!
I am not anticipating any changes to UFC 4 where a replay system will be improved upon, but the team has seen this feedback from the community over the course of launch and will digest it for the future.
Would you want the replay system to do anything else aside from moving the camera angle around. How about an editing system where you can mash short clips together? Overlays and commentary? That would make for some great content for the web, yes?
