I doubt adding jamming would dig RO2 out of it's unrealistic hole. If anything it will just enjoy the skill orientated player base, ideally if there were big, wide open maps to run around like in RO where people might live longer than a minute or so, then yes jamming map be a good thing. Hell i'd love to see a dynamic environment where if you're crawling around on dirt, your weapon's chance of jamming increases and such. Probably difficult to implement I suppose...
