Mostly because I am lazy but
Should we add an "Enchant Fountain" that you can sacrifice enchants you have no use for (or higher end ones. Reason coming soon) for "points"
You can use these points to take a random grab at a "Gachapon Group" of ALL enchants in that rank as this would be the cheapest option
Spend "points" to hand pick a couple you want into the pool. This would cost more but you at least know your choices are in there...somewhere
Or the best one, and the most EXPENSIVE, would be to select a very small group (we can discuss this?) and the let fountain do it's RNG for you.
I highkey want some kind of thing that exchanges the rank you put in with another random enchant of equal rank. Maybe like 2 or 3 in hopes for something else.
