There's a preview out for the first Legacy of the Void balance update. It explains some of the changes that are coming in, and what parts of the game they will affect.
Lurker starts off with 9 range, and upgrade is removed. Lurker attack is also more responsive after burrowing.
The Lurker feels buried at the moment, especially in ZvZ vs. Roaches where we’d really love to see more Lurker play. Against other races the steps needed to start using Lurkers also feels like too much. Hydralisk Den has to be upgraded to the Lurker Den, which also competes with the Hydralisk upgrade, Lurkers then need to be morphed and also research the upgrade before Lurkers are useful. We’d like to try out this change in order to see what happens when Lurker timing is sped up.
