I played a few matches yesterday with an team consisting of lvl 1 to 12 players. Was requesting ammo for some time and didnt see the field ops making any moves, actually he kept running for objective.
Got a little annoyed, did not see his level in scoreboard yet. After I walked to him, called out his name with voice chat and said: " press ‘E’ to drop some ammo please". He jerked around a bit and ammo started flying out of his hands ;).
It was a joyful moment and I expressed my respect for an lvl 1 player dashing out ammo in the lobby after our loss =).
/tl;dr help our community players by simply pointing out the keys and class their are playing, result: heart warming supplies!
