I remember discussing about decreasing the decay-rate of Meson Rifles before, but got waved off for various reasons. One of the reasons was "Mesons aren't supposed to be in the Matrix". True that, but heck, we got people using hacks in broad daylight and hacks are supposedly not visible to blues (at least not as how we see them), so I wonder how blues feel when somebody dies or gets injured from hacks. So IMO the "non-matrixy" argument holds no value.
So anyways, since I know Rare doesn't want to decrease the decay rate on the dropped items in 10 and 01 I propose this:
Collector Binary Boy:
2x Light Meson Rifle MK I -> 1x Enhanced Light Meson Rifle MK I ( additonally: normal decay rate, 1% ball acc)
5x Meson Rifle MK I -> 1x Enhanced Meson Rifle MK I ( additonally: normal decay rate, 2% ball acc)
5x Light Meson Rifle MK II -> 1x Enhanced Light Meson Rifle MK II ( additonally: normal decay rate, 2 or 3% ball acc)
10x Meson Rifle MK II -> 1x Enhanced Meson Rifle MK II ( additonally: normal decay rate, 3 or 4% ball acc)
Also, I write this up because I got reminded about it once again due to a Heavy Meson MK II dropping from the 01 TM today when I farmed him with cookie. Boss drops should be useful, so the Heavy MK I and Heavy MK II should also have normal decay >_< (Maybe trade in 2 for an enhanced version like above with normal decay? The Heavy MK II has a drop rate of 1 / 120 so farming the MK II two times is rather harsh anyways, so it's also kinda fair?)
