Even considering the fact that there are more spell, I still feel like there are too many scrolls spawning in loot container.
It's just my opinion, but I don't think that because there are more spells there should be more scrolls spawning. Scrolls might look banal, but they are in fact very powerful since they count as extra spells. I really liked the fact that scrolls we rarer before as I said before, it was still possible to gather a lot of scroll for extra spells, but it was harder and longer so you had to be more careful using them because you didn't knew when you would get an other one.
Now if I want a scroll I just have to go to the vistani shop in the Mist Camp where the shop is always full of scroll, and these scroll aren't necessarily low lvl spell. I see a lot of lvl 7, 8 and even 9 spell which can be pretty strong for a wizard if they get a bunch of them.
