I don't disagree that it would be nice if there was some way to have in game tutorials to help people learn their rotations better or have more tools to help improve their playing. However, what would it be? How much dev time/resources/money would it take to implement something? What are we as players willing to give up to have this whatever implemented? Would it get enough use to be worth the time and resources spent on it?

Some sort of parser could be nice, but it does come with some pretty big issues. I personally miss having a parser, for my own information, yes. But I have seen the downside to them in WoW, seen people bully others over their performance, and Yoshi has stated he does NOT want that in FFXIV, and I can't blame him.

No matter what might get implemented, there will STILL be plenty of people who won't use it, because they literally don't care about how well they perform as long as they can do the things they want to do in game. The dungeon trolls who delight in doing little to nothing because they know it irritates the people they are playing with, the people who just wanna smack some buttons and get on with the story - I'm sure there are plenty of other examples. The people who do want to learn, want to improve - they ask here, ask in game, look things up themselves. SO why invest time and resources into something that won't really fix these issues?
