You could not have picked a more irrelevant metric. So we're balancing based on popularity now? If you look at the page on a certain site you pulled that information from, you'll see that other jobs like samurai, dragoon, and whm are similar outliers that far outstrip their peers. Guess you're just outta luck huh, if your job is padded with people looking for their 'pure healer fantasy', or people looking to play iconic final fantasy jobs. Here, these are total number of parses per job in Eden2 so far:
Summoner 24,815
Black Mage 13,194
Red Mage 13,834
Samurai 21,945
Ninja 16,560
Monk 11,998
Dragoon 25,837
Machinist 17,712
Bard 14,272
Dancer 16,393
Astrologian 16,236
White Mage 39,613
Scholar 32,653
All sorts of factors affect what job people choose to play. You have reasons like monk not being 'flashy' enough for most melee players, or astrologian being less straightforward than the other two healers. By your logic, we're going to need to buff monk even more too, as if they weren't monsters already.
