Yeah, same here, I'm just going to go for a 1* Apoc(for the 35% dark passive) and then grab as many lances as heart/eye drops permit; and spend whatever leftover lower mats on class points and such. If I get extra copies as drops, it's icing on the proverbial cake.

That said, I am burning all the potions I get; sooner I have a larger AP pool, the more AP I have to spend to get more rank, which leads to more AP. It snowballs, so the faster you get the ball rolling, the sooner it builds up.
