I only play for a month or so at a time every year.. but Hearthstone is my favorite mobile game.
Control Warrior is the only decks I play.

No way, another fellow Hearthstone enthusiast?!
I wondered if there weren’t a few of us around. Playing since 2014.
I can't remember now, but it's probably the same for me. I only do Battlegrounds now when the itch comes to scratch. Very little ladder climbing.
I only ever play standard. Maybe some arena occasionaly.
Battlegrounds seems like absolute chaos to me. 😂
On a mobile, it would be absolutely difficult to play! In general, BGs look overwhelming at first, but I liked the fact that it wasn't so static in terms of decks/meta as it can get in standard. I always look for something new/different and BGs delivers on that front.
