Telling SE to change the XP rates (for everyone) because of something you feel personally due to an apparent love of grindfests and being able to play 4 hours per day every day, and expressing a dislike of a game balanced such that people with limited play time can experience most available content, is in fact speaking for everyone while stating an opinion.

If OP had said "What do people think about leveling rates, for me, I have this much playtime and as a result think that leveling rates are excessive", then they would not have been open to the accusation of putting words into the playerbase's mouth. If there were even something remotely approaching a consensus that people actually /want/ an awful Korean-MMO grindfest, I'd have to reluctantly admit that the OP was not putting words into the playerbase's mouth. As it is, it's the only accurate representation of the OP's statement, and I find it distinctly unpleasant.
