I like the stuff that is in there. 24 man is awesome looks, even though its really REALLY undertuned, and I think the 2B outfit is going to be the main attire for the next months in the game. I personally dont mind the crossover with Nier, but it DOES give the feeling that the Nier universe is invading the Eorzea, and you really have to ignore all the illogical situations (Magic vs. a futuristic fighter jet craft? yeaaaaah right ...) and just go with this as an arcade video game.

I like the new dungeon, especially the last boss was fun. Would love to have a version of that fight that actually takes some effort.

Hades is cool. I liked that we didnt just clear him on the first night entirely, and how the EX version ties into the Heavensward Ascians.

New PvP gear looks cool, even though it further changes the FFXIV universe towards a sci-fi mashup - not sure if this is a good idea, seeing how futuristic designs also were never popular in other fantasy games.

I like the MSQ so far. It retains the high quality of 5.0

Unfortunately, it is such a small patch in terms of actual playtime or content. Its the big "catch up" patch for the lower half of the playerbase, introducing barely any progress but a lot of nerfing of existing content, and all the group activities outside Hades EX are basically outdated content on release.
I had hoped, after the tremendous success of SHB, that SE would learn from past mistakes and step up their game here. This patch lasts a few days for most playable content until you just repeat old stuff, yet its supposed to hold us over for what, another 4 months till we get an actual raid tier?
