2 BST

You only waited 30 minutes. Most English speakers here are in the US and are at work....

That said, two BST can easily duo the majority of non-HNM/high endgame content today. One person to sub WHM to act as healer, one to sub a melee job for extra DD oomph. Two BST can take out everything from Abyssea NMs and bosses to Dynamis.

Meeble Burrows is new content and not many of us are bothering with it. Two BST cannot do today's primary endgame content, such as Legion, Voidwatch, NNI, etc. Those things will still require a a full party or an alliance, and BST are not considered the best jobs for those things.
