Arena needs balancing

Arena is by far my favorite mode. However, it’s been incredibly frustrating lately. Two games in a row, I died at 15 health because a hunter played “collateral damage”. Arena should not have cards that create such a high damage OTK.

One of the reasons I play arena is because it has (or used to have) a back and forth gameplay. How is it fair to slowly take over board and play strategically, only for people to spam spells and minions to the face?

Blizzard seems to have put nearly zero effort into balancing arena. It’s just incredibly frustrating to spend time taking back the board and playing very carefully; only to get spell spammed and lose.

Is blizzard’s general strategy to just continue building a game that focuses only on OTK and aggro? Not fun to me.
