If you only played like 10 games with a Hunter of course you have a better K/D you skipped the trial and error phase since it's not your first character. I'm a Hunter and my kills come from a Handcannon and I shoot 60% precision shots. I only use the GG when I have to. BladeDancer was only OP the first month of the games release, after that it's the second choice for Hunters. I don't complain about PVP much but I noticed how the most skilled players play in each class. Warlocks and Titans have instant Specs that can be used to easily counteract a Hunter. A Hunter has to map out the attack and hope it doesn't fail. IMO warlock/titans with grenades are the most deadly in PVP
