Its not a divise topic at all, almost all DE players has done it and does it still and knows it is strong.
It still is fast, still can move 10"-14" without any troubles b.c the archon is still 8"+D6 (re-roll) movements, thats fast enough. You also dont need to worry about keeping all 3 in the aura range every turn.
I personally always take battalion the kabals will be bubble wrap from DSing, their damage isnt good enough for me to warrent them shooting if there is DSing threats, keeping my stronger units alive to shoot later is worth sacrificing 60-90pts of dudes for 375pts of vehicles.
Vs Imperial that plays anytype of marines, triple D Ravagers is the death of them, we have 2 imperial players and i wont play it against then b.c its not even fair.
