Got my Master Sergeant Silver + Gold last night, but still havent got my 10 heals for the silver badge!!
There was one round where I blitzed it and must have gotten at least 15 heals (cheers for the tip of running about with the hub, it seems to help a lot) but there was no badge award mentioned whilst I was playing the round, and my internet connection died about 1 min before the end, so I never got to see if it came up at the end, nor did it appear in my BFHQ.
Bit puzzled about that, because regardless of my disconnection I should still of gotten the badge, I have over 50hrs with the hub notched up so that's not an issue?!
