I don't have logs unfortunately, so I can't provide real evidence as to what's going on during our fights.
I've joined a new raid team and provide the support role of main spec healing, and off spec DPS in our 10-man raid team. As a healer, my item level is 483. Our other healers are in the upper 470s. They crush me on the meters and I'm wondering if there's more to it than they're able to shield incoming damage. I know the Disc Priest can put up shields, can the Shaman do the same? It feels like I'm idle during fights because there's nobody to heal and therefore my overall healing done and hps are lower than the others. I know I'm capable and my hps is solid when I'm able to stay busy, I'm just not busy very often with this new team. No one is complaining with my numbers, I'm just used to being at the top and it sucks not to be. We're progressing fine and my utility as a solid off spec DPS has my team very happy with me.
For reference, I'm playing the normal style of a Paladin, not the 4 piece PvP playstyle.
