Guild Wars 2

Inscription and insignia should be streamline as follows:
Power = Blood
Precision = Claw
Toughness = Scale
Vitality = Bone
Healing Power = Totem
Condition Damage = Venom Sac
Critical Damage (Ferocity) = Fang

So to make:
Berserker = 3 blood, 1 claw, 1 fang (or any other similar ratio)
Knight = 3 scale, 1 blood, 1 claw
Cleric = 3 totem, 1 blood, 1 scale
Rabid = 3 venom sac, 1 claw, 1 scale
Celestial = 1 of each (can still be time gated, can broken into 2 parts considering the 4 limit crafting slots)
Zealot = 3 blood, 1 claw, 1 totem (still need the recipe in order to craft)
Etc.

This way you have a streamline system where any new stat combo can be introduced and you don’t need constantly add new items that have very little use outside of just a certain stat combo like we have previously seen. A similar system can be applied to Jewelry too. This also makes it easier for players to get the combo that they want and gives a little bit more relevancy to crafting cause can craft what you need. This works within the existing structure and hopefully a quick implementation.
