In my game of Apocalypse, I found it really really easy to snipe out characters, with the Aim orders making the -1 to hit redundant. A particular pain in the backside was artillery with the barrage rule that meant that basilisks and manticores could snipe out characters with relative ease. The worst was when a character was garrisoned, theoretically a way to protect them, but in practice made them much easier to kill.
Has anyone experienced this? What did you do to mitigate it? House rule or change in playstyle? I don't really like the idea of heroic characters hiding in rhinos to avoid sniper artillery.
