Attack and TP Bonus is basically the given across the board for all jobs unless you're super-specialized on one job (for instance, ranged attacked instead of attack if you're hardcore ranger/corsair...but even as an own of Death Penalty, Annihilator, and Yoichinoyumi, I still keep it w/ attack for all the other jobs).
It's just that useful in comparison to the rest.
Is the TP regain only 1 per tic? Seems like a waste if that's the case.
It's generally be acknowledged since even before TP changes happened that this was a waste of an augment.
TP bonus is pretty much a must. For the other slot, I would recommend acc+4 as I believe it is generally more useful than att+4, unless you are OCD about best-in-slot for max possible damage. If you won't use BLU to melee in ilvl content, then att+4 for sure.
It may be more useful for BLU specific to have acc+4 because it's a sword job with pretty much all multi-hit weaponskills, but in a general DD sense the attack+4 is better given the propensity of other jobs using single-hit or magic-based weapon skills. I would stick with the attack+4 myself.
That said, as long as you're taking TP bonus, you're likely doing it right, and the other augment is best tailored to your specific situation.
