There isn't any way however to obtain Token of Siegfried at this time.
One major reason to do the Monster Exterminators each month is for 2 things:
1. 4 Life Insurance
2. 1 Hatter Card
I have actually used life insurances before like a effing madman getting stalker to 99 at Nameless/New World. I pretty much burned my whole supply I had stocked up over the months to do it, but was pretty worth it.
I agree, they shouldn't be that easy to get, they are really fun to have and let you take a few risks that normally you would be punished with experience loss for.
Monster exterminators would be more appealing if they didn't have you hunt stuff that had only 10 spawns of on a map, but its still not that bad as long as you don't wait till the last days of a month.
So if they do have Token+Life Insurance to the shop, it should take many vote points to obtain only a few most each month.
