Dota is pretty simialr to Warcraft 3 in some ways, you are just controlling less characters (or units) at 1 time. Meepo is one of the most micro intense characters since there are 5 of the guy, but if any one of them die, they all do.
Yea Chen and Enchantress can grab creeps right lol? (I don't really play Dota, I only really watch it every know and again because it is pretty entertaining to watch lol).
