Debating whether it's worth the valor to spend points to upgrade a 483 LFR weapon /w Sha-touched socket. Not sure atm...
You should ask yourself, are you killing the light/dark dragon in progression yet?
and have you completed the quest line enough to get the gem for the sha touched socket?
Also in 5.1 there are additional quests from the prince that will further upgrade the gem.
