Hearthstone battleground

I know people have been say damage takin in battleground is unfair. But look here I been playing here and I think its dumb turn seven you take 18+. You play what you got and go against someone who high rolled and have multiple tavern 6. I believe damage should be this. All minions regardless of tavern tier do only one. Your tavern tier is the only one that should change. It’s not fun multiple time you get massive damage or knocked out buy turn 7 or less.
