I think my point is being missed. Golem is very viable, but let's face it, no-one is going to use Regirock and Golem on the same team, it's just redundant. My point is that in the majority of cases Regirock will be the better one to have. That's not to say Golem doesn't have its uses, it certainly does, but most teams would rather take the extra 70 defense (the difference between Kakuna and Arceus), just as reliable SR, and the ability to mould their rock type into something unpredictable over Golem, who does one thing well, but is very predictable.
Also, Wartortle isn't THAT bad. It's a piece of shit yea, but it does get haze, and its fairly bulky on both sides. I'd still much rather use Torkoal to spin, but Wartortle is still slightly viable. Though I completely agree it shouldn't be ahead of Golbat (gawdamn that thing is good, Crobat is an S tier threat in UU, and Golbat is just the bulkier version of it).
PS: SubBU Braviary beats every rock type in the tier basically, actually it beats everything in the tier full stop.
