Earthshaker is my favorite hero of them all. He's incredibly powerful, and not boring as crap like Naix/Leoric and all of those other 3x passive skill heros. I just started playing him last week, and I really regret repicking him in -ar games. I wouldn't dare use him in a 5v5 game because that would be rather painful to keep your exp up early on, which is his weak point. Once you hit level 7, though, he turns into a killing machine. While your hero(s) at your lane take some risks that they shouldn't because they've been smacking you around all game and stay within close proximity to their massive amount of creeps, you charge in, enchant totem to trigger aftershock, cast echo slam to trigger it again, and if they are still alive, fissure them. If they have about 2 waves worth of creeps next to them, you can consider them both dead. Echo slam is very similar to the Lich's frost nova, except that you WANT it to hit creeps. It bounces way more, and every time it hits an enemy, it deals about 35-65 (depending on level) damage to all nearby creeps. If they have 12 creeps next to them with level 1 echo slam, that's 420 damage from that splash alone, plus the 1-2 times it will hit the hero. Can you say GG? However, unlike most heros reliant on spells, he remains kick ass the entire game through. Ehh, I'll let my replays speak for themselves... No deaths in either one.
