I think this is the kind of mentality that is really hurting Smogon right now. People have gotten so used to a metagame where that their is only one weather that they are having trouble adjusting to 5th gen where are multiple viable weather. People have to understand that this is not 4th Gen any more and I think we need to give this new metagame some time to balance out before calling weather broken. A balanced team can still succeed in this metagame they just need a way to change the weather unlike in past generations. This could be done by a pokemon like Abomasnow, or through a weather changing move like sunny day. Just like in Gen 4 most successful teams had stealth rock, I believe that eventually everyone will come to understand that they need a weather changer to stay competative. I wouldn't say this severely limits teambuilding either as it is perfectly viable to find a free spot on your team to place sunny day if your team can't fit a weather inducer.
The truest post in this thread. People have to come to the realization that weather is the new status quo, the new "normal battle conditions". I like the comparison to Stealth Rock, which I think is being used much less this gen, is very appropriate since lacking a weather changer is like laking an SR user last gen. If people are too stubborn to keep up, then they're going to get left behind.
