Okay, so for most of people’s raiding experience, they have been trained to move out of bad looking stuff on the ground.
However, in Cataclysm, they have moved to a system where there is going to be positional healing, and you’ll have to stand inside of “good” ground-covering effects. However, Effloresence’s graphic is a little bit over-done, so now it looks like a slime puddle, especially if you have more than one stacked on top of each other.
Also, Effloresence is down to a 4 yard radius, which looks big, except that it’s really not. So, the beta forums have reports of tanks & DPS moving out of the effloresence procs, because they didn’t know what it was, and it looks more like green lava or Putricide’s slime pools than something beneficial.
The instant-cast regrowth is working in tree form now, which is why some of my pictures are in tree form.
So, please don’t move out of effloresence, or it won’t heal you. /sad face
Personally, I think the graphic may need to get toned down a bit, so it looks less like something designed to kill you (especially when you stack up a couple procs in the same place, like I did for the last picture). Just about anything else in the game I’ve seen resembling effloresence is something that’s going to kill you if you stand in it. I’m not sure they want to train people to sand in green lava, and then move out of the other green lava that has a larger effect (slime pools in ICC and such).
They could also make the radius larger than the graphic, so that when people move out of it, they will still benefit from the heal.
I would discuss the other actual problems with the talent, but it’s hard to figure out what is intended versus a bug in the latest patch, so I’m avoiding making a blog post about it for now…
