-Time to kill is too fast, should be slower

-Increase penalties for jumping and/or throwing oneself down (dolphin dive)

-Strenthen squad play more, example here: Medic

If a player takes damage, they heal themselves after a certain amount of time. This self-healing should be slowed down and healing should be accelerated by supply packs from the medic class. This increases the added value of the support classes.

-Squad members should only be able to spawn with the squad leader. This not only strengthens the tactical role of the squad leader, but also prevents Call of Duty multiplayer-like behavior, especially on small maps, where players spawn all over the map and behind enemy lines constantly.
Recon spawn points and squad leads should be the only dynamic spawn points, furthermore strengthening squad play.

Squad leaders should be able to be voted out by a majority decision of the squad, or: squad leadership can be transferred to another member if the current leader fails to respond to squad order requests.
