I would like to see:
-Orgin get streamlined
-Server latency streamlined
-The damage bug fixed(moving hitboxes will sometimes take more damage than normal, wtf? I know, right?)
-Squad management
-Better spawn interface
This is a beta for a reason guys, some of you take it as a demo or preview when it's actually part of the process. They made it open for the massive data they will get, workload tests, and also to build hype, but it isn't finished yet. They are working hard on the finished version and will have the big problems ironed out by release but we will not see those changes in beta as it's not related to the finished product at all. I've even heard that it's running on Frostbite 1.5 for memory/size reasons. But don't take the beta as an indicator, all your doing when you cancel your pre-order is money not going to development.
