What Does Valve Bring?
Valve's approach to Dota 2 is unusual in that the gameplay itself is remaining almost entirely untouched. "Our first reaction is to assume that [design elements are] there for a reason," project lead Erik Johnson explains. "IceFrog is one of the smartest designers we've ever met. He's made so many good decisions over the years in building the product. He virtually never makes a decision that doesn't have some reasoning behind it and a way to pick apart the logic behind it." This approach means that Dota 2 basically is DotA-Allstars with new technology.

A few things will make significant differences to players making the transition. Dota 2 uses Valve's Source engine, so the game is much prettier. Source itself is getting a few upgrades, including improved global lighting and true cloth simulation. Dota 2's integrated voice chat is a huge step up from having to set up your own Ventrilo server, and the speed of voice communication is very nearly a requirement for a game as team-focused as DotA.
AI bots will take over for disconnected players, and will be available to play against in unranked training matches as well. However, don't get your hopes up for a full-fledged single-player game, though. Johnson says, "Our goal with the AI is just that their experience isn't destroyed just because one person couldn't finish the game."

Riding the Skill Curve
...
At intermediate and higher levels of play, having a poor player on your team who dies frequently is worse than fighting with a man down, as the opposite team gets gobs of gold for picking off the newbie. This has fostered a legendarily newbie-hostile attitude within large swaths of the DotA community. As fun and rewarding as the game is when you're in a match of appropriate skill level – and it can be one of the very best experiences in gaming, without exaggeration – finding those matches has always been a nightmare. It doesn't help that the game is so intense that Valve had to institute a "no talking about the match for an hour afterwards" rule for its internal playtests. The recent commercial titles that more or less cloned DotA have ameliorated this to some extent, but it is still often a huge problem.
Valve believes that the solution to the huge barrier to entry is threefold. The first, obvious solution is to have excellent skill-based matchmaking for both individuals and teams. Valve believes that the work going into Steamworks for Dota 2's release meets that requirement. Second, interactive guides will allow players to do more than just read a guide for their favorite hero that has been deemed helpful by the community at large. Valve plans to allow guide-makers to tie their work back into the game by doing things like highlighting suggested item purchases or displaying useful information during a match.
Finally, a coaching system is being deeply integrated into the game. By logging in as a coach, veteran players can do their part to help out newer folks. Valve hasn't entirely decided on the specifics of how newbies and coaches will be matched up, but once they're together a few things happen. The coach sees the pupil's screen, and gets private voice and chat channels to communicate with them. The coach probably won't be able to take control of anything directly (once again, the details are currently under discussion), but information is power in Dota 2 and having a mentor whispering in your ear can make all the difference in the world.
