Rebirth - Materia Guardian feels like bullshit [SPOILERS]

So today I finally got started with rebirth and wtf was that boss. "Use doublr helix" okay game how do I build atp when I cant attack the enemy and atb charges at a snail's pace. Same goes for trying to hit in when it's climbing the roof. Also the block timings just feel...idunno, way too early? They dont feel consistent across enemies. True, this is probably a skill issue partly but I feel like both Remake and Rebirth had shitty first bosses, as THEY ARENT SUPPOSED TO BE "GIT GUD CHUD" DIFFICULTY. Other than that the combat system feels nice, the changes to blocking feel nice (minus the timings on some enemies) are especially nice. The ATB system will or course earn bad blood from me for not allowing recovery due to lack of ATB. Oh and also binding attacks still sometimes hit like bullshit but that's been a problem in Remake too.
