The different Warcraft cards, some Dota based, others not, made it really enjoyable watching your heroes compete in another mode than the classic 5on5.
Dota 2 as of now is a stand-alone game, but there are a lot of people who wish back for the times that there were modded versions of the mod. Nearly all old school players made the transition really quick and due to both word of mouth and Valve's marketing, a lot of new players took interest into Dota as well.
