The sader really has enough hassles at his builds, dismounting from horse, long cooldowns, missing heal, do you think it is fair to put even a selfdamage at the only useable helmet essence for dps horse?
We are really the only class who can get killed by ourself or lose a saviour with our own skill against us, please take at least this hassle away from the essence, its already a very unfair meta against all the op healing toons.
I think the dismount penalty should be removed when using Divine Struggle as well.
Devs give really a s*** about our class it seems, at most patch nodes we are not even mentioned anymore. Vithus nerf was breaking farm builds, everyone seems now faster then me with the lame horse, at pvp most toons needs only a short contact to kill sader if i have no bubble and if you get dismounted you ran around like a helpless chicken for sometimes 7-10 seconds becomming free loot to everyone. I cant say how bad the developers are if it comes to class balance at this game, it feels they completely gave up.
When you realize that warlock has a 10 times better equivalent essence with no drawbacks 
Ashes of Liberty : 120% dmg/s buffed by movement speed to reach 240% dmg/s + base burn effect
Jawless grin : +38% dmg to burning enemies
Sader’s shield : 22.8% dmg increased or 57% dmg on TLoC enemies
TLoC is not that easy to achieve for this build, depends on Potency/Resistance, limited in time.
I do want the self damage from Annointed Brimstone. It procs several essences by itself. Eg. Divine Protection shoulders - reduced CoL cooldown by 1 sec per damage up to 4secs. Then there’s Trial by Fury main hand, procs by every tick of self damage.
Not saying its great but there are creative things you can do with it. Now if we can remove the 4sec cap cd of CoL using the said shoulder, then we’re in business even though we’ll be kb juggled or cc to death. still something to help sader survivability.
I actually want to keep the self damage as it procs some including the new set. I just want it to stop before it kills us, or triggers glad or triggers savior.
As the crusader has the worst survivability in the game, there really is no need for it trigger any of our only survival mechanisms.
Maybe that would even be the perfect solution, that the essence only can damage us to a certain point but dont kill us or take away saviors. I own the new set now too at sader and its indeed good to control the proc with the selfdps, sadly it takes too oft away my saviors or even kills me in last second thats because the essence gives me mixed emotions in his current form.
