Earth is great Ranged AoE control. Kinetics is great buffing from up close, especially buffing damage. Earth has very little damage. Kin is lots of offense and very few powers that can provide you with protection.
Both sets are very good . . . and together they are OK. I prefer pairing Earth with Rad or Storm, or TA or Therm. I prefer pairing */Kin with Fire and Plant, although Elec and Ice also are good in melee.
I have an Earth/Kin I started a long time ago. His concept was that he was somehow drawn to these unique soil samples in a museum, and actually stole them but got caught. That's how he got his name . . . "Dirt Napper." His name was quite appropriate, as he spend a lot of time dirt napping. Of course, that was before I had really learned how to play the Earth Control set or the Kinetics set. But all the AoE tends to draw a lot of aggro.
LOCAL MAN! The most famous hero of all. There are more newspaper stories about me than anyone else. "Local Man wins Medal of Honor." "Local Man opens Animal Shelter." "Local Man Charged with..." (Um, forget about that one.)

I am considering making another troller and I was wondering if anyone would have an insight on what an earth/kin troller might be good for. (And what might it not be good for.) Thanks!
