What is the alternative? The intent of HLD is to improve your ability to land a hit and deal damage. If the majority of the defenders always have 45 DCI you are stuck with 50% chance of hitting them assuming you are not plauged by HLA and have HCI reduced.
To make up for missing 50% of the time you need to do twice the damage. It would be impossible to double your damage, but you could add a spell damage to your weapon plus SDI on your suit. This assumes you have laready maxed out STR, tactics, anatomy, etc.
Just some thoughts. Maybe think of the problem backwards. Consider maybe you need to lower their resistance instead, which ultimately improves your damage if your weapon attacks to that resistance or using consecrate. In this line of thinking you don't have to increase damage output, but improve the current affect of your current damage.
