I recently painted a Nubian Christian DBA army for my chum Dennis in exchange for this Abysinnian DBA army, mostly Essex I think. The Elephant General is an interesting element to play, it's vulnerable to quick kill by lights, but I used it very aggessively thinking that he's stompy as hell but hard to kill, so just give'r and let the chips fall! Fun army to play, need to be aggressive I reckon, with ample warbands and Jumbo needing overlaps and decent match-ups to ensure they make the most of their q-killing ability.
First 2 games against Nubians were close wins.
