Would you like an in-game parser?

I refuse to go BLM in roulettes because I dont know how to play it.

But see, that's part of our point. Shouldn't you be able to go into something like a roulette on a job you aren't 100% confident with to get more comfortable on it in group situations? Shouldn't casual content like dungeons be more relaxed so you don't have to worry about playing 100% all the time?
