Feedback on the Vaal Grenade Thrower Mob

This specific mob is well-designed to make players hate GGG because of unfair deaths.

1. It throws grenades that deal pretty high fire damage.
2. It throws MULTIPLE grenades, which CAN SHOTGUN.
3. It starts throwing grenades at you OFFSCREEN.
4. THE GRENADES ARE IMPOSSIBLE TO SEE UNTIL THE LAST HALF SECOND BEFORE IT EXPLODES!

See point 3 and 4. By the time you realise you are in a grenade field, it's too late. Either your character can tank it or its goodbye to the map.

I heavily suggest you make this mob's grenades at least 100x as obvious as it currently is. Otherwise it goes against Jonathan's stated design philosophy of more considered and reactive gameplay. Because there's nothing reactive about having to tank an explosion that no normal human being can be reasonably expected to be aware of until just before it explodes.

Perhaps if they were re-designed to behave more like the merc's artillery ballistics -- i.e. stationary, loud, etc -- then the off-screen, high damage nature would feel a bit more reasonable.

A lot of high damage attacks are pretty well signaled with vibrant animations and/or distinct sound cues. This mob has neither.
