Blur users need a melee weapon, a permanent one...
I say why the heck not? Why not create a few melee weapons that are activated by simply pressing the melee button. Like a futuristic katana, hammer, knife, electric batons etc... This would really add a extra layer of awesome to the game, these weapons would not need to be over powered or one hit kills or anything. I see these weapons doing the same amount of damage that is done by hitting the melee button now, hence why they'd be extra special in the hands of a blur user.
Injector Users = Good Melee
Injectors skill lv4 have 15% to melee, so get a Injector with brutal melee synergy mod, and if lucky with a basic melee % with EGO melee perks/skills, with an increase from blur.
with blur, phat slapn is a blast.
