Would "dumbing down" Emperor class titans mean moving some of their linked upgrades (e.g. the Lysander and the half-century) out of Support and into Upgrades? If not, what was intended by the phrase "dumbing down"? In either case, introducing such a pejorative term into the discussion doesn't really present a counter-argument to fixing what some seem to consider a broken unit.
As to fluffiness, one of the few mentions of any loyalist Emperor-class titan I can find is Leg(i)o* Ordo Sinister, which seems to exclusively field Emperor class titans, and be somewhat Inquisition/Ministorum/Arbites aligned. It seems to exist in a sort of Deathwatch/Grey Knights style structure, though I hesitate to mention anything not emanating from Holy Nottingham, nor that which is touched by the hand of Ward

.
Perhaps, if the Gryphonicus AMTL list isn't a fitting place for the build I proposed, there is a case for another list?
*- I seem to find it missing the "i" several places it is referred to, but my rudimentary Latin leaves me ignorant of which is correct (but inclined to avoid similarity to Danish building blocks).
