This patch finally delivers a much needed stability improvement for network games: previously, when the server was sending too much data for the network, clients would fall behind, eventually making their games very unresponsive. With this new update, the server will detect the issue and slow the game down, giving the clients a chance to catch up.
Also, there are finally some balance changes, making other endgame builds, such as phase-bomb, more viable, and also forcing some more trade-offs, e.g. using either "Armament" or "Preloading" to get the full-damage "Ignition Point" later. With the kill streak bonuses you will, in general, have a lot more money available in horde.
