I have been tilted by match after match where I play flawlessly, get kara down to lower health in the late game, and then get slammed by two tigers that have been hanging out in her hand since the opening draw. I get that holding two cards that long would limit options for her, but having to deal with all the provoke, disenchant, and transform it gets very tiring. Sit back and try range?..here comes disenchant and face with bbs spam. Go face?..provoke and bbs spam. Mirror match?..pray to RNG gods…double bbs spam. 
Sure, I could tech in stuff all day and lose to every other faction, live and die a slave to the meta, or ragequit like a three-year old. I’m not a fan of being forced into a corner when deck building. I’d rather stick to my pretentious attitude toward netdecking, but that’s just me.
I have only been successful in winning matches against kara where I went Super-agro-swarm-face, but I don’t find any challenge or fun in that.
I guess I might be crazy but winning in 4 turns just for the sake of winning does not appeal to me as much as a strategy-heavy battle. That’s why I fell in love with this game!
Of course, this is all could be a moot issue when the expansion drops. We can bitch about it until we’re all blue in the face, but it won’t help anyone to wallow in that much negativity. I’ll try to enjoy my little salt pile. 
tl:dr Kara’s bbs is annoying but we’ll see what happens in a few weeks.
