A funny game but some suggestions

Battlefield 6 is very fun and I had a great time playing it, but there are some issues here:

1. Vehicles are too garbage, infantry can easily destroy them.
2. .CPU, my computer is i5 12500h ➕ 3050laptop, There is a 100% CPU usage issue in the game, the same issue happened in my friend's computer,his computer is i7 14700➕4070laptop,which makes global slow motion impossible to play. Not only that, this situation occurs when you open Battlefield 6, and only a few games can be played. 
3. There are always people on the roof, can this be improved?
4. There is also an issue with Battlefield 4, where the campaign is completed but weapons are not given, which has been reported but no one cares about it.
