What's an earth brute??? Did you mean stone?
40 50s so far.
if you dont like me....i dont really care.
respect is earned , never given
I would honestly recommend going against Stone Armor. My first brute was Stone/Stone, and her life to 50 was a hard one. Even IOed out with Incarnates, there's still things she struggles from.
Stone Armor has ridiculously high endurance costs to run all of the toggles out of Granite Mode, and combined with the end heavy Stone Melee, you'll be huffing and puffing a lot. Granite armor itself is a powerful armor, but it slows down your attacks so much that you might as well not even be a brute. (It's good for tank-minded Brutes, but especially with Going Rogue, the question of 'why not just be a tank' is more valid.)
My biggest complaint with it goes with Rooted. Your basic mez protection. Slows you to a crawl, and doesn't let you jump. Irritating in the best of situations, can get you killed in the worst. Jump into a mob because it's too slow to walk to them, even activating Rooted as soon as you get in, some mobs can sneak off a stun befoer you do so. Even with run speed IO sets, it's a pain, and honestly requires way more investment than any set should to become playable.
I'd recommend going with something like Willpower, or if you really want an earth-looking effect, shield with the elemental skin. 
Mostly for concept to go along with my sons "airbender". Just curious how it performs. Only the second brute I have ever made, and I am tired of tanks.
No one pays attention to me, cause I listen to the voices in my head.
