Just like the title says I believe all weapons, armor, and subclasses attributes and unlocks should have stats that are used strictly for pvp and another strictly for pve. Why you may ask? Well its simple and all you have to do is look at this forum and I'm sure 90% of the posts will be nerf this nerf that and guess what 100% of them are strictly for pvp. Now one example that uses this type of system is guild wars. Around the time of the second and third expansion of the original game they were faced with 1 or 2 classes where their skills trees made them 100% invincible. Now instead of nerfing those classes to oblivion they introduced this system giving the pvp aspect the much needed tweaking it deserved without destroying the pve portion because the invincibility didnt work on pve monsters and bosses. Destiny does the opposite and with only having one set of stats they are know to fix for pvp and destroying for pve which I'm sure most bladedancers would agree that you can really only use your super to hide and not fight anymore. That way with a duel stated for pvp and pve everyone can get their fixes without the war between the two groups.
