Back when I used to play (2 years ago) I rolled with a group so I was never really concerned with soloing although I knew we were capable of it and looked into it.

Now I'm returning solo and I know I'm going to have to do alot of things solo so I'm planning to level a /mage for my DRG but I'm wondering which one would be the most effective.

What I know right now about each:

/whm: Has the -na spells, Dia, Regen, Hate, Barspells, self-protect/shell, Auto-Regen, and the highest MP pool (Snk/inv are +'s)

/RDM: Spikes, Refresh, Regen, Bio, En-spells, Fast Cast, Lower MP single target Bar spells, Second highest MP pool (I think)

/BLU: Cocoon, Spells set to give job traits such as Auto-Regen, Spells give stat bonuses, higher melee stats, 5mp fast casting spells, ? (I don't know much about /blu)

I have experience with /whm but not with /rdm or /blu
Which do you all think is the best and why?
