To help set minds at ease Aries_cz is correct! The set bonus remains attached to the armoring mod so as long as you keep the Campaign armoring in your armor, you will receive the set bonus.
I have a question that a guildie posed and i really didnt know what to answer him
If you have a tionese set with any armoring mod on it, once 2.0 hits our servers, if you remove the armoring mod it will now carry the set bonus correct?
What's stopping people from putting a level 10 armoring mod on a tionese set and once 2.0 hits, give that armoring mod to a level 10 alt and pvp with a set bonus? is there a 50 or higher only restriction?
