Most difficult DPS class to play?

[ChaozK]

I think out of BLM, SMN, MNK and DRG, each comes with its own inidvidual challenges and its very hard to make a reasonable argument on what is the most difficult because you cant compare apples to oranges. Do you find it more challenging to time your cast for most uptime? Having a long rotation with lots of skills to use? Having to micromanage a pet and all its abilities on top of your own? Keeping up stacks of a buff on top of a multide of positonal attacks?

Each persons opinion will greatly differ here and there can be points made for each dps to be the hardest.

That being said however, from the sounds of it, the op is looking for a very specific kind of challenge, mainly having a complex rotation. In that regard i would think MNK would be the most fitting class, as in my opinion it has the highest entry skill barrier, due to having to learn forms and positions on top of the usual business. BLM, DRG and SMN by comparison, will give you an easier time when starting out and the challenges will shine through only at the higher lvls of play.

Just my 2 cents.
