As for changes here are the biggest ones:
-Addition of an end phase where only the "winning" team may respawn. There are various footholds and a colossi that the winning team can break open for rewards (rewards not attached!). Those not on the winning team are not forced out of the map, but cannot respawn.
-There is a new flow for getting into Conquest. When it is available you will be able to open the Conquest Menu and select a side for the duration of that Conquest match. If a side is full you won't be able to select it.
-The Conquest menu has received a facelift.
-Conquest Power is now awarded at a set interval during the match based on your personal contribution as well as when the phase changes.
-The decay rate for Conquest Power has been modified so you are not losing it during the match.
-Afk auto kicking has been enabled.
-Control points now have names on mouseover.
-Two additional crafting recipies have been added to all main trades.
You may now craft a portable turret or a portable lifespring.
-Neutral control points now have less health.
