You can just create another character -> modify/customize it on there till you're happy with it -> save the preset -> get on your main -> click on that saved preset and Voila
I think it's close to 1 hour, which even if you can make another char and save the preset, is still absolutely ridiculous.
It is kinda. 30 minutes would've sufficed, an hour is punishment for ***ing something small up. I had this issue with one of my chars the other day--missed something and wanted to fix it, went to buy another scroll only to find out that I couldn't use it for another hour. I got it fixed eventually, after saving the preset and all, but yeah...30 minutes is good.
