Instead of crying for Embiggen nerfs why not pick Mech Paladin, Rez Priest or Zoolock and whoop their asses? Oh I forgot, it's easier to complain about the latest flavour of the month until it gets nerfed (only followed by complaints about <insert despicable deck of choice>)
According to HSR the best performing Embiggen Druid lists deliver a 57-58% win rate. That's far from e.g. Control Warrior in its heyday and the worst offender isn't even Embiggen but Breath of Dreams. The card is #1, 1 and 2 when it comes to Mulligan, Drawn and Played win rate. Embiggen itself performs at the same level as Strength in Numbers which suggests that the combination of mana cheat and ramp is the actual problem, not a +2/+2 (+4/+4) buff on your remaining minions.
Embiggen is 30% of the meta, if you dont see something wrong with it you are blinding yourself from the truth (most likely because you play it).
