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

[Malzian]

A parser is a metric that can be used as an indicator of skill. Note, that does not mean that good parses = high skill and bad parses = low skill... But, like standardized tests, it is one way to evaluate performance. A parser will never capture the full picture off what a player can or can not accomplish, but it can give you a place to start off setting your expectations.

Personally, if I want to know if I'm capable of doing content, I go into the content and I run it a few times. If we clear out, great. If not, try again and see if we improve... And keep trying until you get good enough to clear or realize that you're not ready and need to improve. Many people today, however, want that metric going in because their time is so valuable that they can't even stomach the thought that someone would waste a single second of it trying to clear content and failing.
