Like others have said, its not hard, but what is odd, and should be dealt with, is that mechanics arent initially apparent.
You see a fountain of water on the side, and everyone is like, ok... wtf does that even mean?
Some of us move to the side, thinking of leviathan, and how he would leap out of the water.
Some people thought to stand in the middle of the "lane" they thought was going to show up.
Then I was the person that saw it as "get as far away from it as possible, and step aside, but close enough u might be able to change to standing in the lane, in case u need to switch."
Conveyance is what the fight is lacking.
They can keep the dmg numbers, hp numbers, etc, all the same, they just need a better way to convey what each indicator even means. (the main ones are: tsunami, hellfire, and I forget what the Earthen Breat like attack is called, but the target indiocators should be the lock on, or blue ball above your head, not the orange claw icon.)
If it did that, everything would be fine.
(not that people still wouldnt be messing up, but it would be my main gripes.)
