Will disagree vehemently for skipping out on the +2 set for RDM largely for reasons Ayanno outlined. Time is incredibly precious to RDM. As such, less time spent casting Haste (WHM holds no advantage here) and Refresh II (WHM doesn't get), the better both in MP efficiency and being able to do more. Personally, I can't say I'm in agreement with the sentiment some hold about Adoulin rejuvenating RDM's role as an enfeebler, however. RDM holds no unique debuffs outside of slightly higher potencies for the two that generally matter (Slow and Para). All A+ Enfeebling affords is higher MACC, but BLM, SCH, and WHM don't exactly hurt for that stat or even gear with it and INT/MND on top. Granted, it may be a prevailing issue that those jobs never felt the need to gear for enfeebling in the past due to very little need outside of BLMs in Dynamis. Mechanically, some would argue immunobreak also favors these jobs more than it does RDM, too.
Regardless of my personal stance on the job and how to fix it, you will still be a third-rate healer, nuker, and not-worth-mentioning melee. Enfeebling is a role SE needs to vastly expand upon to even begin legitimizing the sentiment some try to push now. As such, when/if Delve falls out of favor, any and all perceived advantages RDM may hold now will be lost, as the job itself hasn't changed one iota from the days of never getting invites to VW or Abyssea. So, it may be in your better interest to focus on something more popular now, even if it may require a few more steps to get ready. And if you want my jaded opinion, SCH is the "Red Mage" some seem to really crave.
