This should be moved to the archetypes section. Empathy, Pain, Thermal, and Nature are the most heal based sets. Now, how you interact with those sets partly depends on what AT you picked and how how you want them as a focus. A Corruptor is primarily doing blast. A Controller is primarily doing controls which can be deemed the 'best' support, and a Defender is going to use those sets the most with various amounts of blasts in between. Some sets might be busier so they take away from using the support set more. Personally something like Ill/emp plays really well in that Ill doesn't need to be super busy and you can focus more on the Empathy part.
