Melee Smash was made in 2017 (or 2018 I dont remember!!) and it's been a pretty fun gamemode. Here are some suggestions I think it could use.
Rank Buff: I think this will be a good addition in Melee Smash to prevent hackers, alot of low-ranks play MS innocently and get accused for hacking.
New Maps some new maps would be a pretty good change for melee smash, we've had almost the same maps for like a year and it would be pretty nice to get a wide variety of maps to choose from for melee smash.
New Melee New melee's would be another good thing for R2DA so we don't get bored of old melee's.
I kinda won't think this would actually happen in the game but it would be nice if I saw it. PlaceRebuilder really doesn't have to focus on this game mode, it's OK to say the least right now.
