You will not stop great attackers in wars, given all the fire power we have these days. Limiting units doesn't make sense to me. Turret swaps are real easy these days and can be done instantly, so swapping out turrets for specific outpost mixes is actually fun and works against most of the squads in the war queue's these days. Not much effect on PvP, since most attackers are newly maxed Prestiges who can't get past the max gr, let alone deal with the turrets.
