Yeah you get 10 points for a revive. You get double that if you are in the Frago area. Which means you would get 20 points then. When healing someone you get points based on how much you heal them. So, if you only heal them a little bit then you will only get a point or two. If you heal them from near death you will get quite a bit.
You have to be careful sometimes when reviving, as well. Sometimes you will heal yourself when you are trying to revive someone else. You will also revive someone somtimes when you are trying to heal yourself. So just pay attention to the little circle in the middle of the screen so you know what you are doing.
Also, the Improve Revive is well worth the price if winning and teamwork are you top priorities. It will revive people to full health. It doesn't give you any extra points, but it is very beneficial to the person you are trying to revive. This is especially beneficial to both of you if you are under fire. So, I would definitely recommend getting the improved revive at some point.
