In-Game Parser.

[Felessan]

For a game that has a DPS check in majority of its encounters, this is a silly thing to not have.

Majority of encounters does not have any significant DPS checks and the only ones that do require dps checks are raids where people widely use 3rd party parsers anyway.
Now we have a status quo when people do use parsers for their own improvement, but they are not allowed to point out others numbers as it is bannable offense.

Which is bull**** of the worst sort. First thing they implemented with PF was the ability to restrict by ilvl, which is even worse discrimination.

Harassment is not equal to discrimination. People can discriminate as much as they want in PF - put ilvl/clearance requirements, ignore melee players, kick out unwanted persons, even kick people for low dps based on parsers numbers as long as the real reason is not stated. But you cannot verbally abuse people for their low performance and you can't kick inexperienced people from DF group because their numbers are a bit on a low side, that will be a big case if everyone can see others numbers.

On another note, I never entirely understood the harassment claim on parsers being available to everyone. If that already exists at current, with those who have access to it harassing others (not everyone uses parsers for this purpose), why would giving everyone parsers hurt?

Now only dedicated people use parsers and they usually keep their mouth shut about numbers shown (they still can give a commendations and like), because otherwise there will be troubles. And those who can't keep silence will be eventually reported and banned.
If you give parsers to everyone - they'll have no obligations to not use these numbers in offensive ways.
