Basically my suggestion is
WHY DID YOU PUT A COOLDOWN ON THE WISE SCROLL?!
I'd suggest to remove the cooldown.
It's really boring that you have to wait 30 seconds until you can use the scroll again
it has no sense, in lower level you'd be faster if you just spam dungeon instead of waiting that cooldown.
And as i heard that's not only for me
a lot of people are blaming this cooldowns and find it boring
So why don't you leave this cooldown?If you can't maybe tell us the motivation? ;-;
Anyway thanks to people that will reply and support me for this suggestion!
