It depends. Some guns that's my first thing done. Some guns I swear I got tons of bloodthirsties with up until no perks/attachments and then I can't get it done. A couple of times I'd get 8 or 9 out of 10 WITH no perks/attachments, then pop everything back on, and then still can't get it done.

I always do my no perks no attachments at the same time. For some reason by the time I get that done, I usually only have maybe 5 more bloodthirsties to get. So I don't think it's too bad. --- GT: APG CAMO (End of rant, thank you for listening, please visit my site idontcareifyoudisagree.net) - nuschler2212
Besides Combat Knife/Crossbow things bloodthirsty is easy. No attachments on the MK was a real hassle. --- "A wizard is never late, Frodo Baggins. Nor is he early. He arrives precisely when he means to." Booster Defense Force
