Reasons to upgrade from 10 to !!?

I tried to find threads about reasons to upgrade but no luck SO...

What are the reasons to upgrade from Protools 10 to Protools 11
Im not a power user by any means..
still using an 11 rack and an old 002 rack..on a 2011 mac mini 2.0 quad processor
I remember something about MORE POWER :)
seriously though..

Are there more and better different plug processing options?
what am I missing out on?
Don't care about subscribing to 12 right now ;(
by the way..my pt 10 isn't going to vaporize if I don't upgrade to 12 right? :)

thanks for your time in advance!
