u can get ranked commz thru regular WZ too
As a matter of fact, by adding the comms that you get from wining two regular warzone matches to those that you get from doing the daily you could come away with about 225 ranked comms vs. 160 ranked comms assuming that you convert all of the regular comms that you receive to ranked comms. Add in the comms that you get from doing your weekly, and you get the equivalent of another 400 ranked comms out of the deal.
So, all in, you could earn about 850 more ranked comms per week if you just won two regular matches per day.
Oh, and by the way, if you lose all of your matches the same is true, but you will need to lose four matches a day instead of winning two.
