The case for reducing monster corpse explosion range

What is an unfair death?

"A death that could not be prevented without knowledge of an incoming attack" seems to be a fair definition for "unfair death". It is unreasonable to expect a player to always carry a skill gem that consumes monster corpses in order to prevent a rare/unique monster from exploding said corpses from a range that the player cannot see. Currently monsters can explode corpses underneath a player while the player cannot even see the monster using the 'detonate corpse' skill. These attacks are not telegraphed in any meaningful way, and can result in the death of a player due to something that they cannot even see or predict.

Consider one of the many maps that contain choke points. Either the Crypt or the rope bridges map (I forget what its called). How can it be considered reasonable to allow a monster to explode corpses while remaining off screen? This can be easily changed by putting a tighter range restriction on the monster's detonate corpse skill. This would AT LEAST allow the player to see that they are about to fight a monster than use this deadly skill and allow the player to adjust tactics. Currently its impossible to know if a rare/boss mob is off-screen just waiting to detonate a corpse that the player must walk over in order to progress.

what i don't understand is, how can a boss from offscreen trigger a skill in the middle of the screen?

are those players playing on 16:10 monitors where less horizontal game content is shown?

100% agree I'm sick and tired of attacks offscreen and agro area being over the scree, everything runs fast into me from somewhere and shoots from outside my viewport, delirium mobs run from some glass thingy and push me like half a screen back for whatever reason, the game was supposed to be slowed down yet almost every monster is twice as fast as me with +30% movement speed boots, and detonate dead dudes are the worst, I don't even know where they are all I see some mobs becoming red and about to explode and I have like 1s to react
