Maelström Monsters shotgunning

The Maelström monsters in aqueduct seems to do more damage when they have extra projectiles, are they able to shotgun with their skills?

Skills that do not hit simultenously can still hit you in quick succession (tornadoes in academy boss)
Skills that explode into AoE and overlap, can still hit you in the same time. (If the balls are the same ball lighnings, that you use they are counted to share cooldown between hits and thus cannot shotgun)

Most probably what you are experiencing is the rare mob mods (I guess you are not doing the map with/without gmp mod)

I have encounterd this also, feels like it's shotgunning but maby it is as above speaker suggested.
A single ball is no problems at all to take to the face, but met the ehm is it Mutewind faction that has one of theese fellas that lmp:ed me in the face. Instarip basically.
If it is not shotgunning would be nice to know and just learn not to facetank it xD
But if it is shotgunning it should be fixed.
If we can't shotgun nomore, the mobs shouldn't either ;)

Mostly curious about the mech. behind this. Hope somone can give us an answer.
