The Future of Weapon Claim tickets
If I had to guess, I would say they will be one ticket while the skin is “in season” and five when it is not.
Well, you can never guarantee the quantity it would take, but you can be sure to be one step closer to a good looking skin.
I would imagine future weapons will all start costing 1 ticket then go to 5 later. Its the best possible situation, it creates a “rush” to get the skin when they’re first released (which could push sales of BLC chests, good for Anet) and provides some degree of exclusivity since the skins become very hard to get after a while, without making them 100% exclusive and letting people work toward them gradually if they want.
That’s all conjecture, though. There’s been no official word from devs on that, far as I’m aware.
