You mean SE made tuned the end-game boss to be mechanically unbeatable so players don't complete the entire game's content in ONE month after release???

What is this crazyness?!?!?!

Really though...do you realize how much of a joke ARR would look if people cleared Coil within a MONTH of release? SE would never hear the end of it. Three years of redoing the game and 100% content clear within a month. It's no surprise they purposefully overtuned the fight so no one could beat it.
