I've seen the PTS update of bloodmist, ZOS made it like a tanking tool IMO. After the dash, you will have a blood pool beneath the ground for x amount of seconds.. combined with swarming scion.. and bam!
Also, in terms of graphical effects of the blood pool, would it make sense if after dash, all enemies that hit by bloodmist will have a debuff for x seconds and you steal life from them? and removing the annoying blood pool effect.
I am not here to bash it or what, just to make a discussion re to the changes.. since ZOS are kinda saying they're taking ESO to the next level, why don't they start will small changes to combat graphics as well?
