Kambi and QG's are the least problematic SK builds right now. They are both very easily counterable because they are too heavy-focused on one win condition. Once you figure out your opponent might be using kambi, you have two options:
1) hold your d-shackles (obviously, if you have one) and pretty much auto-win
2) pressure the first 2 rounds so he have to spend kambi to win a round and thus loose his win condition for round 3.
It might work on the lower elos, but high rank players know how to deal with those builds without having to rely on specific counters.
Pretty much there are 3 top tier sk builds right now: axeman, morkvag/olgier buff and anti-axemen/berserker. There are some hybrid builds among those too.
All of them run shieldmaidens and a variable number of bears (one to three) for bronzes, morkvag/sig/gremist/donar for silvers and renew/hjalmar/lugos for golds.
If you play SK without one of this cards, you are doing it wrong, unless you are purposedly running a tier 2 build like kambi/QG's.
This sets of bronzes, silvers, golds are extremely powerful on this meta and are the backbone of what is making SK strong. Specially shieldmaidens and the silvers ihmo (no, i dont think bears are the main problem here, although i agree they shouldnt be what they are now).
So, if you guys want to find something wrong with the faction, start looking on those cards.
