Just checking. You said;
+ Intelligence & Vitality gear?
Got a reasoning for it?
Mana & Life pool only goes up with Hard points, you don't gain any from items. (if you don't already know) I understand Intelligence for healing, that is good.
There aren't very many Guardian lovers (or users for that matter) ... I was going to post a lot, but I think you need to check some guides or ask people that can help you better than I. Good luck and have fun, I love the guardian, but I play it way differently than others since I practically only Solo.
