I'm not saying huge power drain beam arrays; however, specially designated cruisers and/or fighters with EMP-reinforced weapons would add a little more depth to combat. And the focus of combat shouldn't be on 1v1, but on fleet battles; groups of friends duking it out, working together to create a more entertaining fight than two ships strafing and shooting, which is all combat is at this point: holding down the left mouse button until the shield hit indicator turns red.
Furthermore, I would support it being, say, capped at 95% or so; that would leave room for tactical depth while still preventing ships from being completely invulnerable.
Also, it's not that hard to make weapons that nullify ions. I recently made a ship of around 800 mass that can empty the power reserves of a ship of 50k mass in under 30 seconds, with room for plenty of other systems.
Finally, "You are probably the only person in this community" is a rather harsh way to state your point. You could get it across much better by simply stating why you think Ion Shields being above 50% is a bad things. I can guarantee that I'm not the only one in the community who thinks this way.
