I rolled a Sorc just for the purpose of healing WZ's and end game content. Currently a level 31 but I find it rewarding when I see how much heals I can put out. It's a new role for me but I enjoy it. I do hate when I put bubbles up on everyone and someone throws their guard up on a dps. Makes no sense. Well, it makes sense because of medals but it can be discouraging not having the same protection you try to offer people.
All in all, it's a fun class in pvp and I love seeing those times when my dps is equal to my healing.
Just wait until 50 pvp.
