It'll be easy and is easier than coil - The guy who makes this game even said it's content that was designed to be ran before coil. You can't realistically argue against the one who makes the game you play. In comparison, it's like saying BCNM 20s in FFXI is harder than Naakauls.

I'll say this much: Given how gimmicky SE made XIV's encounters, it'll only be tough when no one knows how to clear stuff in one go if it has a lot of gimmicks, i.e kill the Elementals on the platforms while standing on the blue panel - It sounds easy but the playerbase SE targets isn't exactly known for listening to directions.
