Rick "Then dont put in the description they work against bombers. They suck against them."
Would be nice if more detail was added to some units...for instance, shadows try dropping their bomb inside shields, Eraser & Aspis are both amphibious (their buildpic indicates this, but it's easy to overlook), Stilettoes instantly drain practically all shields it hits, and anti-nukes only protect stuff inside their radius (doesn't intercept nukes that fly over).
Also, I heard shields are crazy effective protecting gunships from AA due to the fact that AA's normal damage is low (AA has special damage against air units).
