I think there's a slight flaw in people's thinking process. Slowking isn't exactly OP just because it walls hitmonlee and scizor, the only two things that slowking can actually wall (and thief hitmonlee/scizor 2hkos slowking anyways, so um no it's not exactly OP), there are tons of choice banders that take on slowking still. Golem, donphan, steelix, nidoking, crawdaunt, sharpedo, fearow, granbull, kingler, kangaskhan, houndoom, absol, breloom, zangoose, sceptile, azumarill, shiftry, stantler, and ariados (you're welcome gunthug) all 2hko slowking with their cb set. Let's not pretend that slowking walls everything, it only walls a few choice banders such as hitmonlee and a few of the weaker choice banders, and is usually forced to slack off the damage, giving the other person a free switch into anything they want. And like I mentioned before in this thread, slowking can't switch in on walls too easily either, as most of them run toxic such as slowking, chansey, clefable, gligar, and defensive steelix, which hinders slowking's ability to wall things greatly. And the argument that teams usually have cleric support isn't great either just because team synergy isn't banworthy, which most people should know by now.
