Team Deathmatch is probably one of the best non ranked game mode released in Valorant but please remove abilities from it.
It is a great game mode to warm up, practice aim and genuinely enjoyable that you don't have to worry every other second getting shot in the back of the head or spawning in a shit location.
However there is no need for abilities in this game mode. What is the point of deathmatch warm up when there's some pussy ass bitch playing controller and smoking half the map (since it's already half the size of a regular map) and camping the smokes or straight up just not fighting and waiting for you to push the smoke.
You can argue about training with Jett knives and chamber but you can honestly do jett knives in the range and chamber just do sheriff only.
