Lucky you.
I have stopped counting the number of times I died because of that broken feature. And by dying, I mean instant death from an enemy that is not even targeting you, and that has most of the time not even noticed you. My teammate enters some room, starts attacking the monsters around, the whole mob rushes on him, I come next and unleash all my ranged/area/DOT attacks etc, most die, lying on the floor, I check my tankmate health: doing OK, going well, and then my character also lies on the floor, like going to sleep. No hit, no blood, no monster right around, nothing. I am like “what?..”, check the health bar: the bar is empty, no health bar. I am like “WTF?”. The health did not go down, the whole bar just disappeared. I think maybe a bug or something, check the monsters around, the remaining one is another reflect asshole unique, and am like “k…” and respawn.
I take no risk by saying that this is at least 1/3 of my instant deaths in ultimate.
Reflect like it is at the moment is no challenge and is no fun.
The penalty that it represents to glass cannons/casters is way too harsh.
I would buy a mod with reflect sent back to that stinking place where it is from.
The damage reflection should at least feature a visual effect, require the monster to enable the ability and consume energy over time (like any aura, any buff) and/or to target a specific enemy and to feature a visual attack regarding ranged attacks that you can dodge. The way it is at the moment with fully permanent/automatic/energy free/universal/self-targeting/instant/very likely no cooldown/no damage cap/and worst of all no range cap setting is complete BS. I have died sometimes with the reflect asshole out of my screen.
I have no problem with some spiked enemy with flat melee retaliation or something, or I don’t know, some cold or fire retaliation from a visually obvious protection spell. It is part of the monster feature, you can identify it and you deal with it accordingly, that’s balanced, that’s the kind of game mechanics you would expect from a video game in 2017, but OP full reflect on random unique monsters around just does not work. At all.
