@Reichieiu there are several very well known DRG's on FFXIAH AH
Martel, yourself and Orphannus to name a few that very renowned in the community and could have did a much better job than me
No man, you did a phenomenal job. Keep tweaking it with the help of the community and lets make this the best guide on FFXIAH!
As far as /BLU, while it has fallen out of favor recently with the addition of trust NPCs, it is easily the best solo /mage sub if you are going to be taking a ton of damage. RDM and WHM my offer things like en-spells, phalanx, erase, refresh, convert, protect, shell, dispel, ect, but /BLU offers you more bang for your buck when you are soloing anything extremely hard. Foot Kick, the BLU spell used to trigger healing breath can't be interrupted, and there are so many more BLU spells that you can set for defensive capabilities that it was once the /mage sub of choice for anything remotely challenging. You can also set spells for
auto-refesh and other traits you may require.
That being said, /BLU is also so much harder to master because there are so many spells / little things you have to learn. You can even set spells to self-skillchain with.
Who knows, /BLU might come back now that they have added item level WoE. It should be used as a mage sub whenever you don't have trust NPCs and you aren't just "Farming" or fighting old "HNMs". For instance, if I wanted to go solo Achuka, I would probably /BLU. (he is going to kill my trust NPCs anyway)
There are many people that will argue against /blu in favor of /rdm and I love /rdm, but it doesn't compare to /blu on anything with actual difficulty. (which, to be fair, is hard to find anymore)
