So, what I was thinking of a possibility, is too add the ability to spawn on teammates/squad mates. I know, it sounds pretty stupid, but think about it. It's AIDS to spawn miles away from where you died, or if you get merked by an AI. Either that or some type of bed respawn point in the base, I don't know how you'd add these, but it'd be great if they were added.
I am fully aware this can be abused in Combat, but another suggestion is, if you add this make it so if an enemy is nearby, we can't spawn back on our teammate. (Excluding AI)
Another Suggestion is moving the Mercenary base further into the salt lake because when you're driving down the main road from Sofia, they'll lock onto you and completely destroy you. It honestly sucks, and I've died many times from it.
Another is to add the ability to spawn a quad bike in the XM8 Menu, this'd be great if you don't add the Spawn Points on teammates option.
Another, and in my opinion somewhat needed, is to add more "simple" missions, and small missions. EX: Ambush Convoy, Invade (town), Armed Transports, Assassinate VIP, ect...
I have a lot more suggestions, but let's start with these.
