Q: How are you going to handle delay and lag between players? (by Alex)
A: This is something we are putting a lot of time and resources into. Minimizing delay to servers, along with optimizing networking code, is very important to being able to enjoy DotA on both a casual and competitive level. We�re expanding the Steam infrastructure around the world so the matchmaking service for DotA 2 is able to provide the lowest possible ping wherever you are playing. There will also be some uniquely located servers that are optimized regionally for handling longer distance matches.
Q: I heard there was going to be an AI feature for when a player leaves. Is there going to be an option to take direct control of the hero? (by Stephen)
A: The AI features will be optional to the players in the game. You can have teammates use it, send it to the base, or give it AI modes and behaviors to follow.
Q: Are the upgraded graphics going to be distracting? New graphics are great, but when there�s too much, you can�t see what�s going on anymore. (by Lycan)
A: Gameplay is definitely the most important aspect, everyone on the team understands this concern. The number one priority is making sure players can quickly and easily tell what�s happening on the screen at all times. Fine tuning the right visual balance with each ability, effect, hero, etc., will be an ongoing process as the game is playtested and we get your feedback. A clean and understandable visual representation of the action is important to everyone from experienced players, spectators, to new players.
