Some of mentioned the ease at which the Elven strongholds, particularly Lorien, fall to the Shadow. Some have proposed some more radical options for addressing this; my proposal is much smaller step,
BALANCE OPTION: Elven Defenses
When defending an Elven Stronghold, all Elven units (including Legolas, if his ability is used to add to the Combat Strength) gain a +1 to hit (resulting in hitting on a 4,5, or 6 in most cases). Non-Elven units defending Elven Strongholds do not get this bonus and only Elven Leader rerolls (including Legolas) of Elven unit attacks gain this bonus.
