Do the unlock points come from the Cumulative XP's or from the Available XP's?
For example, it takes 290 XP to unlock a Corsair!
Lets say I start with 200 Cumulative XP, when I reach 290 is this when the Corsair is made avialble, or is it from the Available XP's and if so, then to get there one would not want to spend any XP's on purcahse skills?
Please help me out in understanding this.
Thanks
