Considering that they buffed the off-position potency of multiple moves in 4.06, they obviously don't want people to be punished as badly for missing positionals accidentally or simply being stuck in a situation where they can't be positioned properly due to mechanics, so the fact that Trick Attack was left as is rather confusing, because presently, no other class is punished as badly for a missed positional as NIN is, as you're losing out on 10 seconds of 10% more group DPS on top of the 160 bonus potency.

It's made more confusing by the fact that it's presently the only ability in the game that has its buff/debuff tied to a positional.

True North helps a little, but it's only going to be up for one out of every three TAs, and some hunts/bosses are fidgety and/or mechanics heavy enough that I find myself wishing it was available much more often then that.
