Ramuh's music was great, Ifrit's design should have been more beastly, E7 gives me Spirited Away vibes with its paper birds and the teleportation mechanic stresses me out.

As for E8...

Ryne was on thin ice for me (no pun intended I swear) this whole expansion due to her connection with Minfillia, but with E8 I pretty much lost what little tolerance I had for her. She shoehorned herself into a fight that could have had a huge emotional impact given the WoL's connection to Shiva but thanks to her meddling the encounter is irritating at best. The mechanics in which she removes/changes her clothes make me deeply uncomfortable given her age and I am not a fan of Hraesvelgr's implementation.
