If parsing is needed to clear challenging content then why is it not in the game?

[Cenerae]

Parsers aren't *needed* to clear challenging content.

A parser is a tool that is useful for a player/a raid group to analyze the performance of themselves. You do not require the use of said tool to clear the content. But people that want to use one have the ability to use one for the goal of self/group analysis. I don't see a compelling reason why suddenly it's super important to have an in-game parser. The people that care are already using one. Or do you think that we need parsers for 4 man content suddenly?
