Early solo Mind is a great set, as your tier 1-3 powers are your attack chain. That being said, empathy as a secondary won't help you much. Later in the game soloing will go a lot slower, but is still functional.
As for teaming, your main control is Terrify, which, as a fear, has limitations, but is decent at what it does. Empathy brings a lot to a team with 4 key powers... Fortitude, the two RAs, and adrenaline boost. Fortitude should be used on Squishies first and tanks last, unless your tank is the one dying... In which case your team has bigger problems.
