This is how the market is *supposed* to work, except that it doesn't.
No other profession is currently viable in the endgame, bar the few and far in between grenade uses for cybertechs. Everything Armormech, Synthweaving, Armstech and Artifice can produce has either better versions or exact counterparts in PvE and PvP. Oh yes, you can craft the "skins" for your armor, but this is only viable pre-50 at the moment. Once you hit 50, if you're going to start raiding or PvPing you only need consumables, and maybe a starship upgrade or two, if you're still not sick and tired of flying that arcade game called "Space Combat".
Bottom line (and I'm repeating myself here): You don't fix the situation by making the only good crafting profession choice worse. You fix it by making the other crafting skills better.
Tell it to people who spent days and weeks farming commendations.
If it's "just an advantage", then it's far faster to get a set of Columi/Rakata gear, maybe a color crystal with +41 bonus from Kaon flashpoint with rougly the same stats and forget about the repetitive and tedious Valor/Ilum/Warzone grind. Oh, wait, that would kill the whole PvP system for good. See the problem here?
if you follow the logic of "top PvP gear provides too big an advantage" you might as well start thinking in the direction of "Rakata gear makes running normal mode flashpoints/operations too easy" and scrap the whole idea of PvE itemization and progression.
Thing is, if a game is built around obtaining better gear, the better geared will *always* stomp the freshly dinged into the dirt. You want it fair and square? Follow Guild Wars logic or remove gear bonuses altogether, leaving armor as a social "choose your skin" feature only. Otherwise it's a vicious circle.
