Okay.. Anywho, the biggest concern I think for Blizzard DotA is very simple. The limited selection of heroes to use. The thing is, this requires more balancing than that of StarCraft II and there's still a lot of balancing that needs to be done what with the new expansion coming out soon and whatnot. Part of the fun in playing the original DotA map in Frozen Throne was that heroes kept being added to the mix, making it an everchanging and for it to sustain that kind of play value, Blizzard will need to dedicate a special division to manage this shit.. I just really hope Blizzard knows what they're doing.. :|
