Alrighty, so Im gonna roll as a healer on my Guardian im making now. Which Abilities should I be leveling first?

Multi Heal and Salv im messing around right now

Took a look at your character, you seem to have a good grasp on what to buy for a budget healer, not that you asked about that.

As for abilities as long as you have multi heal as your main priority you cant go wrong. Healback can be pretty decent. Keep an eye out for cheap EE clubs and build a set and play around with some damage abilities like knockdown so that when no one needs a heal you can still be useful.

I recommend getting at least a 1-35 club set with EE, for the higher levels a heal mastery weapon is fine as you'll be healing more.
