Wasn't posting your KD in that other thread enough? I know this is just a joke thread and is destined for spam, but w/e
I think part of the problem is that we have quite a split community. Some people want to balance around siege, some battle, some Strat, some even duel. Totally different game modes, different objectives, different lethality for classes etc. Then we have EU and NA. Different spread of classes, different ability of players etc
Reason I say that is KD is only an indication of ability. It depends on what game mode you play, which class you are, which server, how consistent you are, how serious you play all the time etc. Getting 4:1 KD is different on horseback than with an archer for eg, eventhough the ranged player might be just as useful as the cav. It depends on the class counters too. I know cav can get great KD's but I feel that often it is fair KD so its not like you can use KD just to suggest something is OP either.
Last hits are not all that matter in the game, its overall usefulness for your team (archer might be hitting stuff all round but not necessarily getting last hits, and he can be bad at the game and do it) and it depends whether its deserved KD or not depending on many other factors. KD says nothing about how fair and unbiased your viewpoints will be too. You really need to see someone play to decide if they are bad or not, although very low KD would be an indication of that it can't really be used by itself
