How will fewer Vulcans affect the Federation?

[Temis the Vorta]

In the back of my mind, I always assumed Vulcans were a positive influence on the Federation and held human tendencies towards stupidity and agression in check.

So now the Feds will be more dangerous, perhaps a bit like Farscape's Peacekeepers. Rather than being a moderating influence, the surviving Vulcans might lose their logical equillibrium and become vengeful, making things even worse.

if there were going to be more than three Abrams movies, this might be an interesting idea to explore.
