I have healed in ESO for years, and go through phases of DPS. Right now I am really enjoying a stam DPS phase, but I have noticed just how infrequently healers bring sustain support to the fight. I have switched off the Warrior to the Serpent Mundus, on top of chugging pots on cool down, and bringing in heavy attacks.
In the one out of six or seven dungeons that I actually get a healer pumping out support, life goes much smoother. Not just for myself, but the other dps and tank as well. So I just wanted to touch on the two main types, and how they play now from the consumer perspective.
Shards are good for having a stationary burst with a fast delivery. They are great for camping on the tank. Though I need to be mindful when playing stam DPS not to steal one that will keep the tank going, since a replacement may not be forthcoming. The visual effect of shards can also get lost in the sauce of visual clutter in dungeons. Frequently I only know one is there due to the synergy pop-up.
Orbs, man they are even slower now, but that isn't a terrible thing with how they are playing. Extra heals being rolled out for players. Easy to see. And the big one, everybody can get a piece! Ranged DPS, melee, and the tank can get in on that sweet round action. All in all, I find this to be the better option with the changes from Scalebreaker. Just keep one rolling out towards the tank, and recast when it expires or moves beyond the tank. Easy. The DPS will gladly move to touch them as needed, because that extra resource really helps out so much.
So in conclusion, please keep those orbs a rolling and those fights a going! We all appreciate the healers support when we get it.
p.s. Keep up Elemental Drain even if it is just for yourselves.
