Tiny 2v1 ranged heroes? His manapool is so limited he needs to be incredibly judicious with his combo until he gets his farm. He'll get harassed to hell if he tries to last hit. Put him against 2 ranged heroes, say a WR & a OD. Useless. Banished to hell, no mana. Locked downed and harassed by a WR. He isn't OP at all. He needs a Blink Dagger & Agy is pretty much core in him. That's a lot of farm. Na'Vi have been trying to use him but he just doesn't work. He doesn't carry. He's a great ganker with abilities, but late game a Spectre or Weaver will outright destroy him. Sure, he hits hard. Too bad he attacks 50% slower due to Ulti, and a carry needs both Damage & AS to be good.
For me the visual style of DotA2 is great. Love it tons.
@ Swiftero: The game is less forgiving. Definitely. Stick with it though. If there's one thing to keep in mind about DotA, it's the more you play it the better it will be.
@ Dulliath: Agree, Hannover showed some interesting picks and a bit of deviation, but for the large part it was the same. DotA meanwhile you have trilane, roaming, pushing, etc....
I remember a post on Reddit commenting on the differences. In LoL, the towers protect you. In DotA, you protect the towers. Both make sense, but it really shows the difference between the two IMO.
