It would be good to have Talents scrolls for certain occasions, for example I hate to make a baddass rogue with Pet-Pal talent, but I need it to not miss any sidequest; so if I were able to find a talent scroll "Pet-Pal" I could use it only in the animal that really matters to talk with. The loot could be random like special arrows and it could be a perfect way to not be limited for choices that we don稚 want in our builds because we will have the possibility to experiments all talents at least only few times.
