I highly doubt that the spawn rate is .86%. I've found two AS50s, and two M107s. On the other hand, I've seen several orders of magnitude more residential spawns than heli spawns, and have never seen a mt dew can. The sample size isn't conclusive, but I really don't think these guns are as rare as the wiki says. I agree that there are too many high end weapons, but it's not just duping that's causing it. You also have to take into account the lack of a weapon sink. Most high end weapons never leave circulation. If you find an AS50 on a corpse, you're VERY unlikely to leave it alone (unless you already have one) In order to stop weapon inflation, Rocket would have to fix all the duping bugs, and add a mechanic that removes weapons from the system. There are several options for that: 1) Make bodies unlootable, or make weapons on bodies unlootable. This means everyone who dies takes a couple weapons with them. This would discourage team play, since your friends couldn't grab your gear after the firefight. 2) Make weapons degrade over time. After a certain number of shots, the weapon becomes inoperable. This would be highly annoying, but it would work. 3) Remove all storage from the game. Nobody can hoard weapons if they can't store them anywhere, can they? This removes an important mechanic from the game, though.
