The regular content is quite casual generally... I can understand the MSQ and it's relevant dungeons being more casual. But raids, specifically the "hard" difficulty 8-man ones and the 24-man ones, could stand to have more difficulty than just learning the mechanics...

Some fights you could just about record yourself going through it as a macro and just let that do the fight for you next time. Worst offender of this for Stormblood being Catastrophe from Omega's Deltascape v2.0...
