Yes, in the first part of the battle i just run to get into spotting position - do some silentspotting, and see how it develops, what the enemy is going to do...
Then i relocate or engage, beeing sure i do not loose my camo. Still, i am fast enough - my Gun does allow me to stay on a healthy distance, and my Strength (almost troll) is the Camofactor - i try to work with that in the first Place.
The nastiest thing for the enemy is beeing shot, and not seeing from where.. shooting Targets without beeing a Target myself, is what i try to achieve in this little bugger. As i have too little alpha, it is best when i can stay stationary and let my machinegun work for some 10 seconds or more without catching returnfire.
But all depends on the Playstyle ofc - your Setup sounds also good, and matches in combination very good i think - depends how aggressive you want to play the E-25 :)
