Why don't you combine the various training modes you have on several of your maps and put them all in one? Because you have several good training modes on different maps, for example, put everything in this training.01, which from what I understand looks a lot like the current csgohub csstats training map, but that map has been broken for months and doesn't work.
Add the Prefire mode from the Aim Arena — Bot Training map, also add Combat and Target because I think they are very good training modes that should be in training.01.
Add the spray training that is in Fast Warmup.
The KZ of both maps, Aim Arena — Bot Training and Fast Warmup, are 10x better than the current one in training.01 because they are not too difficult but also not too easy. The one in training is very, very difficult; I can't even get past the first part, and I can easily finish the other two and have fun while training my movement.
The Prefire mode from SC Aim Course v3. 0 isn't bad either, you could put something similar in training. 01 The only thing that would change is having a checkpoint for each new zone, because when you die you start over, you should have a checkpoint for each new zone.
The Logitech G Map also has good modes, the prefire one is good, it just needs the bots to shoot and the only up/kz mode too.
There are also modes in the DHL Skills Lab map that you could add, such as the Targets and Grenades modes, and also add the faceit level that a player has in these modes.
But I think the most important ones are the first three maps I mentioned: Prefire, Combat, Target, KZ, and spray training.
Otherwise, I think it's good.
