Ironic how there were petition to ban Reuniclus to Ubers in early BW, and now it's close to dropping. Really illustrates how time can cause a metagame to change.
And I somehow suspect that the release of BW2 might have had a tiny influence on it too.
In the same regard, we were close to suspect test Volt-Turn for its brokenness. The same arguments are now recycled in the weather debate, whereas the loud voices against Volt-Turn have silenced. Things surely do change within a generation, and it will be exciting to see how the current top threats will fare in six months.
