I see you added a system so crafting XP doesnt go to the void.
That is great and good on you AGS!
Now we need the same type of system for player XP. No need to have 3 tiers per aptitude point. Just the regular level up bar. Once filled, aptitude increases by 1 and something happens…GW2 gives a goodie bag, ESO is champion points. Do some research and figure out something what feels rewarding and fits NW.
Edit: This system should include ALL XP, gathering, player, etc… That is otherwise going nowhere on use.
Progression systems are important. Look at the Champion system in ESO that is a huge draw to keep playing post max level.
