How would an optional, official parser be toxic?

[Penthea]

1.) Initially no one asked for parsers in leveling content, only for dummies, ExTrials and Savage. Only Anti-Parser-People are bringing this up, despite the repeated cases of Pro-Parser-People not wanting this in the "casual" and leveling content.

Maybe in this thread but in general a lot of people who want parsers want it in all content. Saying this from my experience in other threads relating to parsers. I agree that parsers are only really relevant and useful at max lvl, especially in savage or ex. But if SE introduce them for that content, players will demand it in the rest of the game too.

2.) Common sense should tell people that an unsynced person is always inferior to an synced person due to the synced person having all main and sub stats synced at the possible cap.

Common sense is sometimes a result of experience. A sprout might not realise exactly what lvl syncing does and therefore would not understand why their dps is so low by comparison. Additionally common sense can be in short supply. Only got to have a look in alliance raids to see proof of this. A lot of people leave their brain at the door when they start gaming.

3.) People just wanting to relax, having some fun time and escape reality have a whole bunch of content they can enjoy, "casual" content. If they decide to leave their house of "casual" content and should be prepared for the rough weather awaiting them their.

I agree but as I said before a lot of pro-parser players want parsers in all content, so this would include the casual content. I understand wanting to be able to analyse your performance from the beginning, but due to class balance while lvling and the fact that the content is intended to be casual, I feel parsers have no place there.
