Well, if they really wanted diversity, they would give us elemental items. This could work multiple ways. Temp boost like rep boosters. Adds an element to a primary for 1 hour (time is irrelevant, could be 24 hours), one element and a new consumable overwrites the previous. Consumable cost 25 or 50 marks, maybe a new raid currency. Another option is to have an item like etheric light, obtainable from end game (raid, coe, trials, ib) it permanently adds an element or adds it until weekly reset. I have 62 ways from Sunday this could work from multiple angles... how about an elemental forge. Single use, permanent, cost 175 marks. Weapons can be forged once, 70 percent chance of kinetic, 10 percent each of the elements.
