This map is DotA Imba Legends v2.0 by Flick
(Dota imba + Dota lod = Dota imba legends)
OMG mode by Flick - Dale BR
Dota imba legends: That Let the Players Can Able to Choose 3 Skills and 1 Ultimate to Combine into 1 Unique Hero in an Epic Battle to Defend the Ancients.
This map is very fun and imba (more than "OMG" map), you try it, you know how "IMBA".
Update new version: Dota imba legends v2.6 VN
