Coil isn't too hard though.
If you put in the practice, you can learn the fights in a short amount of time. The mechanics of each fight are not difficult to understand, and countering them requires slight focus at most. Hitting enrage shouldn't be a problem either, considering that a lot of people who don't run BcoB2 are now hitting i100 on their main classes.

I'm not saying this to try put anyone down. I just wish more people would properly give the fights a try before saying, "It's too hard."
