>>27999395Machamp fissure is only a meme if Machamp has no guard, which he didn't. In gen 1, fissure and OHKO moves worked off the critical hit mechanic which meant that they were best on fast pokemon. Machamp was not fast and neither were most pokemon who had OHKO moves.
Anyways, gen 5 was largely a continuation of the Platinum meta until BW2 which introduced hidden abilities. There were a few new pokemon like Excadrill that were fucking mindbogglingly strong in the original BW meta. Other new additions like Conkeldurr, Hydreigon, Jellicent and Volcarona in particular were solid but didn't upset the meta in the same way that Excadrill did.
Checks to Excadrill didn't come until BW2 which added Hidden Abilities, which turned the meta on its head in some ways. This is when the Smogon meta started to HUGELY diverge from less restrictive formats because auto sun and auto rain came out of the realm of the legendaries on Ninetails and Politoed. Combined with the change to sun that made Growth give sharp boosts under sun, sun teams finally became a legitimate thing. Venusaur and Kingdra were two of the big beneficiaries of this support. The new pokemon Ferrothorn also moved into the spotlight because he was incredibly good with rain support. BW2 also introduced Therian formes, giving us the wonderful Landorus-T.
But more fearsome was the rain team, as the huge assortment of swift swim abusers absolutely loved Politoed support. You almost had to have at least one auto weather pokemon on your team just to clear weather even if you didn't want a weather team. Begun, the weather wars had.
