Would you like an in-game parser?

Again :/ not the point, i talked about training to clear and learn a fight. Because from what i read on other post it's like you can't do that without a parser.

That's exactly what I was talking about! In older games (apart from XI), there was no battle challenge (such as enrage) that parser would have helped you to train to beat. In XI there was and parsers were used for that. In XIV DPS is even more important, as is aligning group buffs and performing certain amount of actions within certain time as well as keeping up high enough activity %. These are things a parser can help you to measure and thus enhance your performance, which weren't present in the older games (and as such, parser wouldn't have helped in learning to perform better in those fights).
