So as an old players i have some suggestions that can help you making game better.
1-Bazooka and greande are too strong , a decrease dmg and blast radious will be very positive to the game
2- increase rifle dmg, rifle always been one of the best weps and more balanced in the game and i could see that its very weak compared to the other weps
3- wepon sounds are very weird and not follow the wepon change in game , looks like delayed
Thats some things that i found by playing the (CBT), hope that helped to upgrade the game
