As someone who's strictly played a caster class since EverQuest, WoW, and now FFXIV - absolutely. I finally got my rotation down on my DRG, right before taking a break from the game for 6 months, which means i've totally forgotten what I learned and now I'm hesitant to take the DRG into dungeons XD Gotta get some practice dummy time in or maybe some Feast action to get me back into the swing of DRG.
