Rogue is the best class and always will be. Other classes should enjoy the show while they can. Rogue is recovering from the nerfs right now and is coming back to take over the meta.
Content creators must be trying very hard to avoid rogue or build bad rogue decks for it to have the worst win rate of all classes.
It's like in WoW PvP. Most of the time, you never kill a rogue. They either kill you before you realize it, or they Cloak of Shadows, Vanish and Sprint back to bandage up while they wait for their cooldowns.
That's just how it goes. They will be back. And they know what your spec is now.
