I play both factions but lately everyone has been calling the KT's fat for no reason whatsoever.
They're more muscular and stocky than fat, other than their belly. Their arms are literally all muscle that is bigger than some other races torsos or heads. Same with the legs and back, all refined. Their biceps are bigger than Goblin heads. With a few more face customisation options, accessories etc, it will be very possible to make them look imposing and strong. They actually look like they would have a fist fight with an Orc and have a good chance of winning.
That said... I was hoping for the Vrykul, but this is also cool.
