In-Game Parser.

[Ehayte]

A parser is like a hammer.
Both are tools. - A hammer is used to build. A parser is used to read out numbers.
Both have constructive uses. - A hammer can help build a home. A parser can help improve where a player is weak in their rotation.
Both can cause harm. - A hammer can be used to bludgeon someone to death. A parser can be used to call out weak chains in parties in a malicious manner.

NO MORE HAMMERS!!!! SHUT DOWN HOME DEPOT!

Also, if my malicious manner you mean in a mean way, then yeah. But calling out a weak chain in a party is VERY useful.

"Everyone gets a trophy" is for Animal Crossing and Farmville. FFXIV can be a very competitive and complex game, we just want the tools to make ourselves better.
