Rogue, unlike the best decks in the meta, actually requires a degree of skill to play making it a no go for the majority of players who are used to "play things on curve; win". Mr. Yagut hit ran from 18 or so to Rank #1 Legend with an almost 90% win rate this season.
That's top of the ladder though. Rogue is my favorite so I watch a lot of Mr Yagut because he plays so much of it...but had to switch off a lot this month cause he switched off rogue to rank up to legend every time I tuned in.
Some of the advantage of rogue is there are lots of people who have no clue how to play against it. Even at rank 5 I have people leaving my minions alive when they could easily clear, overcommitting buffs on something that just gets sapped, etc. Mistakes no one used to make when Rogue was popular.
