Given that the 2 variant costs 75,000, and the 3 variant ticket costs 375,000 (5x the cost for not much gain), it would be really great if knights could incrementally upgrade the tickets they buy as they can afford them.

For example, a knight buys a 2var ticket at the 75,000 price, and later on after they can afford it they want to upgrade the same item with a 3 var ticket... that knight could have the price reduced by the previous ticket price(s) they purchased and had already applied to that item. So the 3 var would cost just 300,000 (or 285,000 if they applied both previous tickets to the item) and until then knights would be able to use the 2UV tickets without having to pay twice over when they wish to upgrade.

I understand the need to keep UVs rare and that is why the costs are so high, but incremental upgrades would greatly help knights as they start out and they wouldn't have to pay twice over just to continually increase the UV status on their item.
