Wild meta always shifted. Pirates, otk druids, evens, odds, giants, mill types, deathrattles, tons of different reno decks, togwaggles etc. Big priest weakened once when Barnes nerfed but it has returned with blood of ghuun. Raza priest nerfed and returned.
I'm ok with all the shifts at wild but i can not accept secret mage kingdom. It has been so many years she ruled and she is still getting stronger and stronger with every expansion. Blizzard needs to overthrow her immediately.
When someone mention about this big priest and secret mage is op there is always a guy who says "play X deck, it's crashing secret mage and big priest. Don't cry and play Y tech card". You think you are a genius but i have a news for you, we all know those things can counter it but we hate this because those decks forcing us to play something we don't want and they are killing the diversity.
