can i exchange regular comms to ranked ones somewhere, even though im below 50?

So im just leveling up a character, and doing a lot of pvp, for fun. Now im maxed out on regular wz commedations, and so i thought i could turn it in for one of the lvl 50 rewards, and just let it sit in my bag until i hit 50. When i approach to buy it though, it says i have to be lvl 50 just to buy the thing, which is dissapointing. Ive been looking around to find something useful to spend the commodations on that will not be useless one i reach max level, but i cant find anything at all. Any recommedations?

This game really needs something akin to Alterac Valley in WoW or something similar, with large scale battles over a big battlezone. Small warzones are charming and all, but there is a very special feel to a large scale pvp battle that any mmo or competative multiplayer game needs. Ive heard that they cant do them because "the engine cant handle it", but surely that cant be it? its 2012, WoW did it and that game released 2004.

Especially for jedi, most of the armors look the same, there is very little variety in how people look. Hood toggle would help a bit with this, especially for those who simply do not want to hooded look but have no choice. Its been basically half a year since the game released, is the hood toggle coming in 1.3? It should, right?

So i was under the impression that jedi shadow was primarily a melee class, but what dissapoints me is the lack of melee abilities. You have your basic attack and the double strike. Thats about it. You have some highly situational attacks besides that, kick, that AoE saber strike and backstab. Its kind of dissapointing and boring to look at when you see the jedi knight class, without skills, have maybe 10 or so. Combat looks way less dynamic and varied because of the lack of melee abilities i feel.
