No one was being rude. If Blaziken had so many simple counters, he wouldn't have been such a necessity to ban. Bringing him back won't accomplish anything either.
As far as PO is concerned, Blaziken has achieved Salamence status (immensely popular, very familiar, on every other team, etc.). And besides, the environment is so different, it's not even funny. DW tier gets Baton Pass, so it naturally spends less time sweeping and more time passing boost to its teammates. I don't play a lick of Wifi, so I don't know what's going on in that respect, but there's just as much to counter it over there as there is over here, because it operates on the same rules. Point is, PO is a different community with their own Pokemon metagame, and their decision-making holds no bearing over ours.
If you really think this, you must not have been on the Smogon server much, where it was able to sweep at the drop of the hat even after we'd worked so hard to keep it in line. There are different players there, and possibly just not enough people repping him properly. On paper, he's the best sweeper in the standard metagame. In practice he's...the best sweeper in the standard metagame. Cut this PO logic bullshit out.
EDIT: Oh yeah, and Swift Swim is still legal in all tiers. Maybe everyone's just too busy getting fucked by Rain to care about Blaziken.
