Guild Wars 2

I play my warrior with a hammer and really like her that way.
I want to spec her defensive, with healing shouts.
But I’m not sure how much healing power I need to be a good group healer.
Someone an advice?

Roll a guardian, please don’t try to be a group healer on warrior

I wouldn’t recommend it for PvE but if you have your heart set on it then you don’t need more than you get with your points in defense. I wouldn’t invest in any healing gear but I would run Soldier Runes. If you are going to heal you might as well cleanse. If you play WvW with that build your group will love you and any organized guild that you tag along with will be than happy to have you around.

How much toughness do I need?

For PvE, 0, just learn what to dodge. If you plan on running in the frontline WvW hammer train or an organized group, 3.2k (about 2k toughness) Armor is recommended.

Follow Julie Yann’s advice for WvW, but please… please never use a hammer or soldier runes in PvE. Do yourself a favor and take note of

Julie Yann.5379:

For PvE, 0, just learn what to dodge.

A properly timed dodge roll nullifies any and all damage taken within the window from start to finish. As well as that, it works for an evasion with whirlwind on GS (#3) too. Instead of wasting your traits and gear to enable you to stand there and absorb damage, you should strive to learn how to use weapon skills, utilities and dodge rolls to your advantage.

WvW sure, that’s a different story as you’re dealing with other human players and the fights won’t be as predictable. Still, I thoroughly discourage attempting to heal with a warrior. It’s ineffective by comparison to what guardians are capable of doing and it greatly inhibits your potential to excell in other areas.
