Monster Haste/HasteAura Mod on "one shot mobs"

So what i've become super annoyed with lately, is there are numerous mobs that have abilities which are designed to do super large amounts of damage but should be "telegraphed" Usually fairly tanky mobs as well.

When those monsters have Haste or Haste Aura, and at times I've seen them have both. I can't confirm if the aura and their haste mod stack but by god they are ultra fast.

So what happens, is you walk up to a pack, and they scream across the screen instantly and do an instant attack with their massive hit, that IS NOT LONGER TELEGRAPHED cause the haste makes it instant.

Suggestion for improvement, let them keep the haste for movement, etc but telegraphed hit attacks need to have haste either reduced. I feel the haste mod is set to basically change SKILL speed, which then impacts the attacks animation frames, instead of reducing the cooldown, I'm fine if it's a bit faster on slams, but right now it's just insanely fast. To point of exceptionally hard to see.

Usually it's a pack of tall Monster warriors and one yellow you don't know about yet, just instant drops a massive hit, and you see the death screen, Look and go oh heh, hasted... I've checked my map mods and it doesn't make a huge difference if there is monster speed or not on the map, the attack frames just disappear. Which for a normal hit is ok, you have some means to offset the damage, but on attacks built to try and one shot you, but as an offset should be telegraphed are losing the telegraph component due to the haste.
