Monthly CC cost for PvP Passes = 960
Say I bought the $9.99 pack for 1050 CC.
So it costs me $9.13 for monthly PvP pass. That is not less than half the sub cost.
I would also want to spend 1700 CC on two unlocks for action bars and artifact equipment as an extra cost.
It's like 8 bucks a month if you buy the 5500cc pack. Plus, if you are a busy person and happen to not have time to play, you can choose not to get a pass and just do the 5 WZ you get for free. That will mean even less money spent for you.
