Lock Weapons behind classes

Don't make this mistake pls.

We are in 2025, the nature of FPS games now is to do high kills and get advantage over others. I already see that once people figure out the meta weapons and perks/gadgets they are going to use only those and everyone will be running the same loadout, and its going to be boring as hell, here's an example: 

The recon class has C4 to counter vehicles AND a movement sensor gadget (its op), you can equip them together; conquest matches are going to turn in CoD domination with VSAT perma on cause half the lobby (if not more) will run recon class with the best assault rifle. Plus if you enable compass, you see the spotted enemies and their exact direction and movement without even looking at minimap...

I might be wrong, this is one very likely scenario tho. I'm scared its not going to feel BF in the long term.

What do you think ?
