I already have the badge chest too, I know you can ticket a GM to get it reimbursed, but I don't have 4 264 tokens yet, and by the time I do, I should have plenty badges to go around anyway, and expertise item will be usefull anyway. I also have the crafted boots, but I might not make the defense minimum with all 4 items without defense (don't forget the gun).
I am kinda wondering why you are using 10exp/15sta gems. 30sta or 10dodge/15sta is superior. Expertise is nice for threat, but it's hardly needed.
Titanium Plating on your shield also seems like a bad choice, unless you have it specifically for anub-25m hardmode add tanking.
