Q:
what about futher elite spec?
Considering that Colin said we will have more than enough points just by completing the challenges in the jungle, you are probably safe to unlock the current specs and still be well on your way to the next ones when they come out. If you have any desire to play part of the current specs then I wouldn’t wait, who know when the next wave will come out. That said if you have absolutely 0 interest then you could potentially get a good head start when the next group of elites comes out.
It depends on how it’s unlocked. The first elite spec is locked until you complete all of the core specs, so it’s always possible that a second elite spec could be locked until you complete the first.
Personally, I don’t think it’s good idea to save the points for a couple of years on the off chance it might let you unlock the next elite spec instantly, when there’s enough spare points to get halfway there anyway.
