Go wilds if you are gunna arena cuz they are cheapest, do not go wilds if you are gunna go full-cata healer because you will overheal like crasy

I love focused. I know how much i'm going to heal for every time. I can keep my buddies in cata's at a certain health, and know that when I heal them - they will be safe.
Wild's are abit, ...wild. You can hit a heal for 1k, and then hit the next for 100. I started off with wilds though, and actually had alot of fun with them. Watching the crits will always give you a grin. They're an awesome price too, compared to Focused.

I made my first Guardian for 50fg, lol. He was AWESOME. Guardians use to be my fav type of char.

Goodluck
