At last the Earth Hammer:



Often you can see this happen at the raid: People running to the far edge to minimize damage (behind the green line). The orange line means medium damage and red is instant death. For the solo (or first) Earth Hammer it's the right decission. For the Triple one not, because of the purple AOE which comes after. People in the orange area take medium damage (with shields or self damage reduction not too much; Mana Shield yay!) but can easily avoid or react to the purple AOEs , while the grouped players only have one direction and often place a death trap for the others. Either sprint (if you haven't sprint used before) or die.
