I have recently swaped out my Aegis for a Bastion with Barricades x 2, Quadcannon and an escape hatch. (and Void Shield if I have points to spare). it gives me a strong hold that provides two spots to keep tanks in cover and a quad cannon with a much better LOS coverage. And the Bastion itself is more resitant than the 10 cultists I normaly have on the Aegis.
Now I am sure their are some army's that will murder the bastion but for the most apart it has been a game winner for me.
I have to agree with this. I have a bastion and an ADL. When I have played on a flat board like that described I have found that my smurfs have been nerfed when facing AP3 weapons (in particular against some nefarious competitive players at my local club lol). Since playing with the ADL, I have been combining it with 1/2x vindicators, a TF cannon and scouts manning the quad gun. If I run the bastion Ill take dev. squads aswell, manning the battlements and taking shots where possible with 4x LC.
Generally running with a librarian i usually give the dev squad prescience
, twin-linking the LC. It never gets old watching those expensive tanks get taken out. However
, once the bastion goes, so does your cover. It always pays to give multiple targets to choose from, so the enemy doesnt focus on a prize unit. May be against the grain for some people, but it pays to have a disposable squad in your force, drawing fire away from the big guns. Maybe not in games <1000, but must be considered if you use such a firebase.
Back to the matter at hand, Id say the ADL has worked pretty well for me since I purchased it. Excellent vs. flyer-heavy forces, and not too bad as a firebase and instant cover for heavy firepower if the opponent has high AP weaponry of their own.
Just remember to spread the forces out, and cover your flanks/rear from D/Strike
