CSGO FFA deathmatch servers are the pinnacle of how I expect deathmatch to play. I get that the current version is more for people who aren't like hardcore into shooters and are new, but they really need to give an option for people who like DM to train. It's currently super inefficient to train when you have the respawn timer and not enough people in the server. The spawns are pretty spaced out that I always have to walk around to find someone when I just want to be constantly taking battles and improving aim. I don't care if I get shot in the back if I can respawn immediately and get back in the action. It's already honestly super sweaty anyway, and maybe it even improves the experience for the causal players because they play the current version and the tryhards play the faster paced version.

Aimlabs and the other third party games are alright but if you like make a workout analogy, training on the base game is like your compound lifts and then other aim trainers are your accessory workouts. Training on Valorant itself is preferable because I believe it translates the best to your actual gameplay.
