Yep, had a couple of good rounds with you tonight. Like I said, if we had 5 of us in squad cooperating and one of us as commander talking in the party chat too I think the hardcore would be a walk in the park. Everyone else who isn't coordinated will be blind as they have no map and no enemy indicators but we will have a major upper hand being organised and with a commander talking to us.
I solely play hardcore CL maps. If me and my mate squad up on voice we can easily sway the game. Only time it doesn't work is when you see matching clan tags on other side. If you had 4-5 ppl on voice in a squad it would be pretty simple. Could work in pairs and really push home an advantage.
