Mo(healer)

If I was going to build an Empathy character just for TF support, I'd go with Emp/Sonic Defender, and concentrate on recharge. That would provide more powerful buffs from Empathy, plus add on -resistance debuffing from Sonic. Leadership pool Assault & Maneuvers, plus probably Tactics.

Add on Superspeed and a +stealth IO, and there's the equivalent of invisibility without wasting a power selection.

I have a hard time disagreeing with this; although any Illusionist should be an asset on a team regardless of the secondary; Ill is just that good. I do have an Ill/Emp at 40; I rolled him up in issue 3 when I first started playing and thought "healz" were uber. I discovered that I absolutely despised playing an emp... the only reason he got to 40 was because there were several times when he was the only character I had in level range of the rest of my regular buddies. Now he's been moved to an unused server (during the free transfers in December-March) and may or may not ever be played again.

But hey, just because I didn't like the set doesn't mean that you won't like it and Illusion is a fantastic primary... it's strong enough to cover for a weaker secondary. I still think that if you're building a character for Mo TF's that there are stronger combinations than empathy; I know I never look for that myself. Yes, it can be effective in good hands but other sets bring more to the party.
