I am finding it annoying that my two handed swords cant take on the appearance of a one handed sword. I find myself doing more damage with two handers in fury, but I hate the size of two handers. sometimes two handed weapons can be so big that they go into the ground and it looks downright stupid as a night elf to have a sword that is almost the same size as yourself. I am purposing that blizzard make two hander to one hander transmog as well as main hand to offhand transmog. also it would be cool to see mace to sword transmog. i have a friend that is a rogue and he is the 6th best geared rogue on the server. he is a sub rogue and yet he would like to transmog to his quel'del'ar, (no idea how to spell), which is a sword and when he plays combat and he hates having to use fist weapons because of their looks. I believe its a good idea to be able to make these interchangeable.
So, if I understand your question, you think it's unfair that you can't transmog 2h to 1h, MH to OH, and Fist Weapons to Swords?
My 2 copper is this: tough cookies. If you play a warrior and hate how big your swords are, you're in the minority. Almost everyone I know who rolled Warr did so so that THEY COULD use the biggest baddest weapons in game. As far as transmogging MH to OH, actually yah, that's kinda shitty; I thought you could do that. So, you have my vote on that piece. But transmogging fist to swords? It's like saying that I really really want to wear the female version of Black Mageweave, and protesting that I can only wear plate. If you don't like the look of fist weapons, don't play a class that uses fist weapons.
