Return of Reckoning

I'm kinda struggling to understand what my role exactly is as a 2h Grace WP, I try to stay in melee to buff/heal and deal the slightest bit of damage, but i do very little and get bursted and murdered instantly, and if I ever back away from the fighting i am useless, what am I doing wrong?

Yay! Bello sapere che ci sono altri italiani che giocano! Ho appena scoperto RoR e sarei felice di unirmi a voi! Se volete sono Kaderic in game! Ciao!
