Rogue has gotten great cards consistently, yet Rogue fans are always doom'n'gloom every spoiler season.
And it's not like Patches hasn't been a rogue staple since MSOG.
Having played since beta, rogue actually got very few good cards in sets until around league of explorer.
In GVG rogue got tinker oil, but that is about it. I don't recall many strong rogue cards in naxx or BRM. Mediocre cards, perhaps. Mostly bad cards in grand tournament.
Does OG have great rogue cards? Not really. Maybe shadowstrike. Swashburglar is good from ONIK. GVG has some strong rogue cards, many niche though.
I think you've greatly overstated how rogue get consistently great cards.
Add in the fact that every rotation rogue loses great cards.
Personally I never thought rogue was in a bad spot coming into this season. I knew quest rogue had high potential and even miracle rogue, called sherazin's strength right off the bat.
