Yes, but a couple of blocks and protection don't make a full healer. Mesmer doesn't have a proper ally healing weapon like a lot of the other specs do. Inspiration does have some heal via traits, and I do like the mantra preparation heal. However, it's not on the ammo, even if at a lesser amount. I also find Healing Prism and Illusionary Inspiration to be underwhelming. I would love to be a primary mesmer healer some day.
