First off, great posting of all those stats!! I love to see compiled lists like this! I have all 3 classes but I run a titan main. I've used all 3 in the crucible and have over a 1.0 k/d on all of them. To me a hunter seems op at times, until I am the hunter that is, then it sucks! I agree that your knife should 1 hit kill for a headshot, not sure why is doesn't. The bladedancer needs to drop more orbs when carving up the enemy, 2 or less is not right when you kill 5 enemies with it! I don't use trip mines, hate them, but in my opinion they last a little too long after being placed. To be honest I hate the lightning grenade also, don't use it, never will. I run a titan main and I agree it lasts too long also. Shoulder charge, as others have stated, is very limiting move as far as vision and window to use it are concerned. I can make it last longer with some really crappy exotic legs but I don't think its worth the slot. As others have said a shotty will ruin our day though! I don't use blink in the crucible because I can't use it properly, not afraid to admit that. Some people are godlike with it though and this is why I see blink as op, hunter or warlock. In my experience people blink through supers, rockets and pretty much every other form of damage I can dish out. There are ways to counter it, you just have to pay attention, but I think its okay for it to be a little op on hunters as they can't seem to take the damage that my titan or even my warlock can. All in all I believe that all classes are balanced fairly well, it just comes down to how you use the weapons at your disposal.
