I can complain about the 2e year Experience Scroll being 20 again and that it doesn’t stack, but instead I was thinking why not give my point of view how to solve the problem of those scrolls getting stacked up and being almost useless for players that have been playing the game for 2 years.
My Solution:
Put an npc in the game (Example: the Birthday vendor with an extra tab.)
where you can use your Experience Scrolls to upgrade them to either:
1: Trade the experience scroll for x amount of Tome of Knowledge.
2: trading 2 level 20 scrolls for a level 40 tome
3 level 20 scrolls for a level 60 tome
4 level 20 scrolls for a level 80 tome
or something like that x+x = something usefull
