The main reason Sun is 'less potent' is because sun is such an overpowered force, that every single team is prepared for it, to the extent that other teams can tear them apart due to over specialisation.
Nothing has actually happened to make sun less broken. However, I am of the opinion that we should wait for Victini to go to OU [Inevitable...] before we give Drought the boot, because, let's face it, Victini is a large part of the problem.
Even without Victini, as my team is showing me, Sun is a top-teir threat, and may even still be broken, even then, but I still think we shoudl wait for Victini to go, ot, failing that, ban Victini from UU first, as he is by far the worst offender under the sun.

Also, while there's been a lot of talk about Mischevious Heart Murkrow [Tried a set myself, wasn't disapointed, but it lacks special bulk], has anyone tried out Moxie Honchkrow? With a Dark Gem, Sucker Punch is an excellent way to get the first KO, and from there, well, Honchkrow was BL in Gen 4 for a reason.
Too bad MoxieKrow misses out on a few vital 4th Gen moves, particually Superpower. However, once Steels are out of the way, MoxieKrow can be pretty deadly.
... Unless you're like me, and always Sucker Punch instead of Persuit, or vice versa. I'm dreadful at predicting with MoxieKrow.

Also, no, I highly doubt there will be an Alderon-style ban for Drought.
Why?
- The Drizzle OU ban was because Swift Swimers were broken under infinite rain [But not Rain Dance]. Other playstyles, such as non-SS offense, and Rain Stall, were not broken. Before anyone suggests that Sun can stall... I ask them to get a grip on reality.
Or wait for Leaf Guard Meganium. Which I am actually looking foward to. It's like Hydra-Rest... except with Leech Seed and Toxic, allowing it to stall anything except Ferroseed and Ferrothorn. Scary. It's not like it's frail like all the other Leaf Guard mons either. Although it still dies horribly to Fire.
- An Alderon ban here would not solve the issue. Ban Chlorophill + Drought? Victini, Charizard and Typholosion [Scarf Eruption under the Sun 2HKO's Slowbro, dealing about 70%. Just to put it into prespective how bad that is], are all still broken. The latter two may still be viable in UU without Sun, and the former would provobly go to OU anyway. Either way, Vulpix would wind up banned anyway.
