Some of us have invested a lot of our energy into doing the job that drops Katanas as they were the strongest offensive weapon. Now with the introduction of the Golden AK47 and their much higher attack the Katanas are now useless, unless you're going for low upkeep, which isn't really worth it since the G-AK47s are significantly stronger. I don't think you should be able to buy stockpile items that are stronger than the strongest drop items. Part of the incentive of doing the various jobs after you've completed them all is to try and maximize your mob with the best drop items. If you can just buy better ones with cash then everyone is just going to spend all their energy on the job that pays the highest cash and it will just be a boring, thoughtless task. I recommend increasing the attack of the Katanas to be more than the G-AK47s or lowering the attack of the G-AK47s to fill in a hole lower down in the chain. I also think the Exoskeletons need to be adjusted. The massive increase in upkeep over the Tactical Armors isn't worth it for a mere one point improvement in defense. With the current fight algorithm and my 1000 mobs, the difference isn't even noticeable.
