I tried that a bit. Seism is all right, but like any on-deploy ability, it blows if he's your only champ on the draw. Similarly, stone barrage is 20 damage to a single champ every 3rd turn. That's pretty low throughout, although it's a decent burst ability at decent range. It seems like maximizing his survivability with absorb and keeping him on the board longer gets more benefit from his other abilities since it's 5 damage plus a knockback per turn. But maybe I'll go back and try it again. Was it always 5. I went away for that expansion and seem to recall it being more like 3 before?
