I've played my share of shifters. My stance is they aren't broken, they're just boring is all. If all a necro got was PWK and it worked 80% of the time, would you say he was underpowered, or just lacking in versatility? I'd hope the latter. Which really just translates to boring. Now if you're really coming out ahead 95% of the time then I can think of only a few possibilities. You're fighting an armadillo one on one. You're a damn good player. You fight complete retards. You only play hide/camo characters who only step out of cover when prepped out their ass with a couple friends. You're exaggerating, a lot. I would say my average pk ratio for shifters was 9-1, even saying I'm an above average player that would put average at say 5-1. Now why is that? Because while shifters may not have a pletora of options, they are good at what they do. Ever try to out damage a ram? Out dodge a mongoose? Out run an eagle? Even assuming you are whooping on a shifter, how hard is it for them to get away? And since they have maybe a whole two choices on commands they're able to reengage pretty damn quick if you try to run, unlike those bash spamming warriors. I don't play shifters anymore, but again, it isn't because they're broke, they're boring. You want something that requires a little more thought go play a non-sword-spec-giant-bash-legacy warrior. If all you want to do is type murder bob, shifter is probably the class for you.
