I just finished ! (Spoiler free stuff ahead if you wanna know what I think)
But... I actually really liked that fight. I'm not sure that "easy" is really the right word for that fight, myself. I think it's... kinda like a math test. ( I know, weird comparison). But if you study your heart out for a difficult math test, then take it and didn't break a sweat, would you really call it easy? I would say its more that you were prepared for a difficult task. I'm pretty sure he would have kicked my ass coming out of the great plateu , assuming I'd dodge all the dangers involved with getting up there. Just my opinion. I still actually quite loved the ending!
