LotV closed beta starts March 31
Also includes detailed list of all changed/new units. They have a new change to the oracle I hadn't seen before that seems like total bull****, because they totally weren't good enough already: a bomb that they drop that explodes and traps nearby units in stasis for 30 seconds.
I actually think corruptors are going to be pretty OP with their new void ray-like ability. They also gave vipers an AOE damage spell that will probably also be stupidly good. On the flip side, I hate that the good things Zerg are getting (lurkers, ravagers) have to be morphed, at a cost, from roaches/hydras, and swarm hosts are going to blow and the OP stuff above will be taken away from us once everyone cries enough.
