Currently most lower books are just trash that we throw away after raids. It’d be cool if they had more purpose and there was more of a market for them so newer players had it a little easier buying what they need.
My thinking is that maybe you could collect 20 of a book to upgrade it to the next tier. This upgrade would be untradeable, of course.
It’d also be cool if you could use this to trade up to relic books, i.e. increase the cap one more level so that you could get +15 for an engraving, though that’d likely have to come much later on in the game.
Or, let people exchange it for different engraving of the same type (combat and class type). Of course ratio could be 5 or 10 for 1 if they’re not feeling generous. But it still better than nothing
Then make the exchanged book as bound or bound to roster. Scarcity still there but people at least can progress themself slowly but surely instead of just now that you need to buy everything. Its also part of the reason why rmt will be more relevant, its not the whole problem but it helps the problem expand
I think if they make improvement on the book its a W
