Being a 208 single phase service I don't see any issue at all. You might kill the power lift the GEC and carefully bring on loads while measuring the voltages from L to N.

So what are your thoughts on the GEC? I had over 20 amps at one point, why does the current just not use the grounded conductor back to the transformer?

The GEC is part of a parallel path. The current will flow on all available paths. The amount of current on each path is based on the impedance for that path. The path with the least impedance will have the most current and the one with the highest impedance will have the least current. With 20 amps, I would expect that you have a metal water pipe as a grounding electrode providing a metallic path to another service that is also using the water pipe as a grounding electrode. In this type of installation you will often have 25% or more of the neutral conductor current on the water pipe.
 
shut the power off to the house and see if you still have amps on the GEC. someones neutral could be missing and they are using the water pipe as the neutral return path and its just happening to go into your panel up your neutral back to the transformer
