Would you like an in-game parser?

[Legion88]

It needs to be in all content. You don't learn to dps in end game. You learn to dps then go to end game and learn the fights. Why deny console players what pc players already got?

In general people should figure out a decent rotation while leveling and practice on a dummy to learn it.

But in leveling is just a low gain out of a parser because of missing skills.
Also in casual content it really isn't needed. I'm running dungeons to get into the jobs flows in duties so i wouldn't want to be judged by my performance in a job i haven't mastered yet or i play to relax, that's what casual content is for.
In SSS and higher endgame content It is a complete other thing, cause it is a kind of competition.
