Also, if you're going to get that earth elemental going, here's an ability that didn't quite thematically fit with my character (plus, i had already made him quite powerful at that point), but is quite swell for a zoner overall: a ground pound, seismic shock so to say. If anybody tries to harass you back or rush in, you can just launch an earth shaker to throw them off balance and disrupt any action they're doing. And heck, it's just as useful up close for the same reason.
