Here is a weakness in many of the arguments presented here about difficulty of the fights and learning the 'mechanics.'

The fight mechanics in this game are almost exclusively based on very specific patterns.

Learning one pattern does not prepare you for the next fight. The next fight will have a different pattern.

Once you learn the rotation for your job, the rest is memorizing the different patterns for each and every fight, and reacting to them quickly enough to move (or pre-emptively). When put that simply, yes, that makes this game very 'easy.'

Easy, but not at all forgiving. One mis-step, one mis-remembered pattern, and one player dies because there is no room for forgiveness in these fights, in many cases, even with the echo.

This thread has come up many many times before, and I agree with the OP only when it comes to Coil. Extreme primals need to stay difficult. I already know I'll never do those fights. Coil needs an easy, without loot mode so we can participate in the story. Please do not insult me by telling me to go to youtube, please.
