IMO, a Leveling Frame system with resources would be best Example: Austringer Adaptive Frame A Level 1 Adaptive Frame gives 20% of a perks potential Lvl 2 30% Lvl 3 40% Lvl 4 50% Lvl 5 60% Skipping a couple... Lvl 9 100% (normal potential) And a Maxed Lvl 10 Frame would MW it and allow you to put the MW of your choice and Enhanced traits without charging you again. For level 10 it would cost about 100k glim 100 Legend Shards 100 Resonant Elements (cores) 10 Resonant Alloy (prisms) 1 Acendent Alloy (Golf Ball) "Crafting is endgame" lets at least make it feel rewarding...
