Are DPS check mechanics too biased against mages?

You have to wait til it's about 20-30 seconds til cast before doing that though.

You have to really time your slide casts well and take some risks.
I do it all the time and my main is BLM DPS.
I haven't done any of the EX's to give feedback.
But those who use to complain about slide casting...That thing is your best friend.
