Heres the thing, all classes exept for operative have a buff. Kinda unfair in my book.
Remove speed buff of medics, nerf it and make it standard kit buff of operatives. Slight speed upgrade until you die. Would be a favourite of heavies im sure.
Right now it looks like (from watching streams, yes its that obvious) operatives are doing their own thing. Sure that might be the idea, but surely an operative could offer some more concrete and reliable in terms of teamwork.
