Don't get me wrong, the capes are invaluable so I understand the point. Ambuscade is 8 years old though. If you've been active for a while then you're done.
I wonder...
an acc tp cape
a high buff tp cape
a ws cape (for each ws you use on that job)
a DT/idling cape
a DT tping cape
and magic casting capes etc
Assuming you only made 5 capes per job and you started the day ambuscade came out and never stopped, you still wouldn't be done all the jobs yet by this month since they only let you complete 2 capes per month.
