Please you beautiful and sexy dev, bring us back classes xp and leveling

For me, if weapons remain locked by class until release, it would be great to return to the grind system based on class and weapon type rather than level. 
This forces players to play different types of gameplay depending on what they want to unlock, and also forces them not to play only meta weapons, giving them a sense of satisfaction at each level and with each new gadget. 

For example, if you're playing as an engineer, it's logical that you feel like you're improving at that and are rewarded with a new toy to be an even better engineer. The same goes for recon, vehicles, and the old assault where you could get strike drones and classic cool LMGs.

Without that, players who grind 100% of their levels with a single assault rifle will only try the best gun for each class and will never play anything else for more than 15 minutes before saying “that's a trash gun.”

And that's less important, but it was very cool to get weapons and a bunch of stuff (I don't mean cosmetics) locked with missions like in BF4 Hardline and 1.

I hope that people who think otherwise will come and engage in constructive debate under this post. were all here to get a GEM game. 
thanks all and have a nice day !
