Guild Wars 2

I though I was almost maxed in healing power sitting at 1063 with 20 in Honor, full exotic Cleric’s and Sapphire Mithril Jewelry. I have been told that it’s possible to get about 1400. I know I could get another 100 from Honor 30 and a little more with Exotic Jewelry as well which would bring me to about 1200. Where does the other 200 points come from?
