Yeah, i realised that when i saw they they had removed merc comms. It made sense pre-patch but you'd think they would have leveled out the exchange rate after the patch. You actually lose 2/3 of the value, which as a hyperthetical, if we say you had 1000 merc comms, that would be 3000 warzones, of which you could only get back 1000 warzones in value, thats 2000 warzone comms lost, which even if you do as well as you can in every game you play will still take you 20 games to get back, but as an average more likely 25 - 30 games. That ain't cool!
Anyway, only way around this that i can see is to log a ticket and hope you get back what you worked for, otherwise just bend over a barrel and let them take you.
