I actually like it because it sets the model scales on our Clan server (!SoS! DeathHouse J+v4.3)
Skins like Vader, Chewie, Leia etc. are set to resemble the characters on the big screen. I hated visiting servers where all the models were the same height. It looked and felt very cheap. Sometimes we allow clientscaling (for a short period till it gets crowded), but only to mess around with clan members and rogue associates, but not actually fight and duel players that way.
And, yes the yoda model is difficult to fight with especially if skillmode is on. Because skillmode ranges damage from different regions of the body.
e.g. head strikes deal more damage than arm or leg stikes.
hence, yoda is harder because his head is much easier to reach. But that does not rule out that will good skill you cannot beat opponents with the yoda or short models.
