I've always been the type of player where I want to master the controls asap so I can focus on the gameplay. I feel that if my attention is on the buttons I am pressing and what does what, then it is not where it needs to be in order to play the game well. Without question, I am at my worst in this game when I am focused on my rotation. I will get hit by the most tell tale telegraph a boss has to throw at me.

I much rather have good encounter design with interesting mechanics. This in itself will force me into a right/left brain dance where I still have to be mindful of my rotation while doing the mechanics. If either side slips, I will screw up. I could either totally botch my rotation, lose my place on the battlefield, or even lose where the boss is at in its mechanical rotation. A good example of this was in Seat of Sacrifice EX when I would forget which element the WoL had imbued his blade with, and Golbez's Gales 2 has been one of the most difficult mechanics for me to deal with because of how much he can mix things up. It is much easier for me to deal with that mechanic as a healer than it is a melee DPS. But the mechanics make such encounters a blast to do. I enjoy them a good deal.

That being said, learning a new job has always been really fun as well. Spending time getting the rotation down, and then putting it into practice in PvE has always been interesting and a bit nerve racking. A job like BLM can make casual content a lot of fun due to its style of gameplay. I honestly couldn't imagine taking that job into harder content, and give a lot of props to the players that do and do it well.
