Actually, it was supposed to be 10 classes in one, however, this has apparently not been implemented in practice yet.
‘Old-school’ Freeze Mage or Malygos Rogue? The recent Frost DK, although I’m not that familiar woth modern Standard?
And now, to the substance of the matter. 
Ah… One should probably know better than to disprove a random moron, as they put it themselves, on the forum, but the one you pointed out is so tempting that I confess — it’s hard to resist, I’ll get into it. So, here we go…
Oh, yeah. Since when is Ben Brode considered a classy designer who understands something about balance etc, as opposed to wild ‘RNG’ effects and ‘BWAHAHA’? 
I’ve already written about him and why some players remember him fondly (spoiler: by comparison), got really nothing new to add and don’t wanna repeat myself.
For a more detailed review of some of Ben’s ideas and fallacies, which also touches the aforementioned theme of ‘variance’ and randomness, you could watch this video by one ‘Old Guardian’:
I’m not necessarily endorsing him, nor do I always agree with him on some matters, but in this video, he makes some good points and provides good arguments, while also scrutinising Ben’s particular views and delusions thoroughly, so overall I would recommend it for those who are interested in the subject.
But this is just a warm-up…
3x3x3=27, by the way, although it might be too ‘exalted’ for those Modern Educayshun victims. 
Oh, and it’s ‘maths’, by the way, so bonus points for ‘literacy’, but that’s not the point. As I was saying, if you consider that, as per that film, ‘1+1 = multiculturalism’ and ‘3x3 = gender equality’ (oh, and if you think those characters from the short film linked above are grotesque — you should have seen some of the posts or topics by this one Well, I suppose this topic also serves as an illustration to a certain extent), then this formula from the ‘genius’ level of numeracy, which is supposed to define the class design (dunno how — maths too stronk here, I guess), isn’t that astounding in comparison at all. So yeah, this just goes to show the level of ‘expertise’, for starters…
To paraphrase it a bit, ‘I’ve got no clue what’s going on, but a friend of a friend told me something, so I’m gonna present this as a basis for my undoubtedly expert and incontrovertible opinion. Dixi.’
Let me point out one more obvious thing, just to be crystal clear: it’s perfectly fine to present one’s opinion corroborated by facts, solid logical arguments and so on, and you don’t need to be a qualified game designer to do that. Unfounded wild claims, on the other hand, backed mostly by calling others ‘morons’ etc, are less so — that’s the whole point.
How fitting… And not surprising at all. Not only do all of those forum morons, to put it in this character’s terms, think that they are someone, that they have an OPINION and everybody should get down on their knees and pray, having heard this ultimate verdict about anything in the world, — but also they have quite the self-esteem, almost literally showing that ‘Ignorance is strength’.
And I can totally understand why. I could also add how some people nowadays are proud of things they used to or are supposed to be ashamed of, including ignorance, but that’d probably be a big digression.
Yeah, no irony in this at all.
Well, at least, to be fair, I’ve also got to point out this (a slippage, perhaps?):
