I've read a few forums about damage vs shield with no definite answer on HOW damage interacts with it i.e. Damage of weapon drains x amount of energy from battery (more damage, more energy lost per hit), although this seems to be the most likely interaction. I feel there should be a change that a shield has a flat amount of energy taken per shot, but still negates, providing more viability for high fire rate/ lower damage weapons making building less about big guns but a little more thought into your weapon compliment, even if splash damage from explosives, and perhaps even put some more balance into damage types, lasers=bonus damage to shields, rapid fire weapons=drain them faster/just less damage overall, explosive splash=shield pierce but modest damage to armor/part underneath with above average damage for direct hits, solid-shot/non-explosive=bonus damage to armor/parts. Still make the higher tier weapons powerful. but not make a handful the go to for every build, every time. I think it would help balance out the combat a bit more and help expand the variety of techs, coerce builders to create more specialized builds.
