Thanks for your feedback. I probably worded my question poorly. I know they are useful, especially as compared to other gear set bonuses, but are they true difference makers? Are the set bonuses truly noticeable in action?
People pay millions to upgrade their gear to 61/63, which gives less of an upgrade than you get for free from that set bonus.
When you get campaign gear (or dread guard), you can put the armorings in any other light or adaptive armor and still get the set bonus, but until then, you have to live with the tionese-rakata look.
If I'm forming a raid and see that you lack the set bonus I will flat out refuse to take you, even if your gear is good enough for the content anyway since it shows that you care more about vanity then doing your job properly.
