I think it is after last patch, or last 2 patch. I experience this at all mode and at all times, even editing deck is very laggy. I click once to edit card and the card is resolve after 2 seconds.
I cannot play battleground. The animation is freezing all the time. I cannot even spend all mana. The time is running out, while I do my things.
The tavern brawl with mana cost to health is frustrating because I click many things, but the animation is freezing all the time.
