I would like to start off by stating there are a number of things I like about the Dynamis update. Cheaper entry is nice for my linkshell's sponsors. I definately enjoy that there are new challenges in Dynamis. It is the difficult hellhole that it always should be. That being said, I would now like to draw a comparison; from the old Dynamis to the new Dynamis.

We just defeated Arch Tzee Xicu Idol, the new megaboss of Dynamis - Windurst. (If you don't want spoilers, hit back on your browser now). He's a blm mob with about 40k HP. He popped manafont and began spamming random aga III spells which did over 900 damage each to melees with maxed out shell V on. Defeating him yielded us the following: Mujin Tento, Mujin Necklace, and a Gold Beastcoin. I'm not even kidding, a GOLD BEASTCOIN. No new KI, no title, no fanfare, and certainly no jadeshell. He was extremely difficult to pop, and extremely difficult to beat, and we get less for beating him than we would get soloing a magian trial.

The comparison between old and new dynamis: These exact same people we just beat new Dynamis with could do a full clear in old Dynamis - Windurst, yielding over 400 whiteshells (thanks to the TH changes) and a random number of jades. This run yielded us 29 whiteshells, and the katana off the megaboss was the only item anyone even wanted. Salt in the wound, the crafting items that drop from dynamis are now worth 1/10 what they used to be worth to NPCs.

TL;DR: I love that there are new challenges in Dynamis, but the reward is disproportionate. Dynamis is harder now, and we get less out of it. Difficulty vs. payoff is way out of proportion.
