Anyone who says those aren't good enough gearsets, to participate in anything beyond that point is ridiculous and you probably want to avoid anyhow. After acquiring all this gear you'll be MORE than well off enough to participate in the new Delve or Skirmish content.
My problem with them is how little haste the set has. Karieyh has 10% and Thurandaut 11%. An easy +5% on a belt 7% if your on a twilight job. Nobody should full time in 15% haste. The collective 61str & 55atk is nice but your TP set & WS set is not the same set. And if it is. Then you're probably not ready for Skrimish or Delve.
We're not looking for ideal sets here. This is about meeting the entry level requirements. If this gear, which is clearly intended to be entry level gear to the new content, does not serve that purpose then something is wrong in Developer Town or something is wrong with us.
