Yea, I get the class that class diversity is a good thing, I was just thinking it would make sense it the 2 front line classes could support each other a little more. I don't find myself using the deployable cover too often and I was thinking of what else I would prefer in that slot.
Liberation is my favorite map from the beta, but C isn't just a strategic choke point. It can be an impregnable fortress if a foothold is developed early enough. It gives far too much access to most of the other sites. If you know what you're doing on Lib, you can completely lock down the game.
Regarding you issues:
I like the auto spotting, but I think it needs to take longer to "spot" an enemy. Put a little more risk into it so Recon played aren't just farming assists for free.
There is a small amount of bullet drop, but I do think there could be more. Maybe well notice it more on larger maps though because most sight lines in the game are inside 200m.
Sniper glint needs to exist for balance. I don't think I would change anything about it currently.
Engineers have a good amount of rockets. In fact, if anything, I would buff rocket damage to vehicles. It's pretty easy to keep a tank alive with just a couple torches on it.
