Battle.net outlines planned changes to the recently launched co-op feature in StarCraft II, as Blizzard discusses changes to enemy AI and balance changes intended to improve the experience. They explain the AI will now employ a much wider variety of tactics, which should enhance replayability. The balance changes will be aimed at improving some of the commanders that were underperforming. This will involve improvements to Raynor's "rapid recruitment," buffs for Kerrigan's survivability, and a few adjustments for Vorazun. They also unveil new decals for co-op achievements, but at this point don't offer an ETA for the changes.
