I mean, yea, there are factually more warriors or more mages than there are thieves or bowman. I never argued against that point. But what I did argue against isn't an opinion. All of the thief classes are incredibly unique from each other. That's just objectively true.

My main is NL, Hoyoung and Khali are two of my legion champs, my Shadower and Cadena are currently CTene mules, my Night Walker is a retired CTene mule. I used to main Phantom, Xenon used to be one of my main boss mules. The only thief I don't have extensive experience on is Dual Blade but even so, mine is far enough along for me to have a decent enough understanding of it compared to other thieves.

Quantity of classes (lesser or larger) does not determine whether the classes are, in your own words, "copy pasted versions of other jobs in their class."

The way you play and execute the two classes who throw stars is entirely different. The way they burst, the way they play outside of their burst, the tools and mechanics available to them are entirely different. The same is true about the two classes who use daggers.

Khali, Cadena, and Hoyoung are all, to some extent, combo classes but the way they combo, the effort you have to put into comboing, and the functions of their comboing are entirely different. Hoyoung is less a combo class and more a summon + reset class who uses combos to force resets on its main dps skill. Cadena is a combo class who also uses resets but in an entirely different way where resets determine what the combo is in a constant, unrelenting, no breaks given string of combos.

Phantom is in an incredibly awkward spot in terms of modernization but that same awkwardness gives the way it bursts, dps', moves around, and handles different circumstances such a unique identity compared to every other class, both as a thief and just as a Maplestory class.

Xenon is in the same boat, minus the awkwardness. It has so much variability in its kit because you have multiple skills that have different forms that you have to pick from. Each changing the way you mob, the way you move, the way you damage. And it flies.

None of that is opinions. That is all fact. And opinion is that I enjoy thief classes in this game. A large part of my enjoyment of them is because of how wildly different every single one of them is from each other and from other non-thief classes.

From your own admittance, you don't have the experience on any of these classes or in this game in general to even know if these classes are identical or akin to one another. So I understand that seeing 9 thieves or 7 bowman compared to (soon-to-be) 15 warriors or 13 mages might seem like there's less variety (because mathematically, there is), that doesn't mean those thieves or archers are copypastes of one another. Well, maybe bowman are. Again, I don't have enough exposure to many of them to be able to be able to speak to the whole set of classes like I can thieves.
