New Tomestone

[VitalSuit]

Poetics is so you can gear up for (and easily plow through) previous end-game content and gear up for HW content. Law is the soldiery of level 60 gear, easy to obtain but not that great later on (right now they're the best 60 gear you can get aside from the ravana ex weapons). When esoterics comes out they'll be better than law but be time gated much like poetics was to soldiery and before that soldiery to mythology.

EDIT:

Actually Law Tomestone gear is the equivalent of Darklight gear from some of the first hard modes. DARKLIGHT GEAR. That crappy i70 gear that even hero's gear replaced with mythology.
The power creep game too stronk.
