This is something we're actively looking at. We're looking at Area of Effect lethality vs cover, and also looking at how squads interact with cover. Squads that are really spread out don't benefit as much from direct fire when in cover, whereas clumped squads can be damaged more heavily with AOE weapons while in cover.
Short answer is yes, we're looking at this from different angles.
OH THANK WHATEVER DEITIES
Just wish it was far sooner of course...
