Ok so obviously
Tier 1 = 1-9
Tier 2 = 10-19
Tier 3 = 20-29
Tier 4 = 30-39
Tier 5 = 40-49
Now once I hit lvl 9 or 10 I choose ny class. Am I still able to craft the items that aren't in my class? Say i become an Outfitter, can I still craft scrolls and such? I would presume yes, as long as they are not above lvl 10?
