To be fair: I like the supernova class - and the torpedoes on the void stalker (because the original rules let you choose between launch bays and torpedoes) - and the weapon battery on the hemlock (because the model represents that).
So, i could say: "I like eldar MMS without eldar MMS rules." ^^
I am just to much "into the fluff" for MMS, i think. What also means that i am not questioning "if the MMS-system works".
