It's kind of incredible how steeply P3S escalated compared to P1S and P2S. The back-half of this tier was loaded with some crazy new mechanics they threw back-to-back-to-back with little time to breath, from Fountain of Fire into Flames of Asphodelos, to all the memery surrounding Pinax and Act 2.
I'm definitely looking forward to the next tier, since, while the craziness is exhausting, it's certainly memorable and exhilarating to conquer. I just hope the next four fights have something that sinks their hooks in me; none of the fights in Tier 1 grabbed my attention like Leviathan and Titan did in Eden, or Halicarnassus and Exdeath did in Omega.
