They rose the cap because the gear is basically worthless now. Other than collection purposes, Stormblood is what? 2-3 months away? If Stormblood follows the same template, the gear will be useful for the first dungeon, be similar to what is in the 2nd dungeon, and will begin replacement by the third.
So don't burn yourself out. I would change perspective, and say "hey I want to complete this armor set" and go with that mindset. If I remember, they never allowed 2.x currency to rollover to 3.x. They just used it for old gear. Likely scenario is poetics will merge with Heavensward currency to reduce UI clutter.
