But then I wont be able to benefit from set bonus if I use orange?

Wow, hell of an answer, thanks a lot for all the details. One question, why shouldnt I augment the war hero set pieces? What should I augment instead then? Edit: I only have sorcerer

After a long time, i logged in today. Back then, there was daily ilum battles (0.5 fps) and we used to get battlemaster gear by opening bags etc. I reached valor level 76 and quit.after around few months after launch. I have full battlemaster gear. Now I see that servers have merged, there are new sets (war hero and elite war hero) and 2-3 new warzones. What should I do to advance my gear? And what are the things I should know? Thanks
