I played it on elite once, solo. It took a long time to defeat the invuln/lr enforcers in the missions, especially since they just as well have been dodging every attack I threw at them with the already high dodge% being increased even further. This was also at a time where slower attacks were easier to dodge(which made force cascade useless on elite mode, so I used a build relying on quicker snappy attacks, and since ranged wasn't so hot then, that meant melee).
