I have been having some fun with this beta. I do think the lack of a server browser and how difficult it is to team up in this is going to be an issue though.
Looking at that hack vid, I'm not surprised 3rd person view is so effective when the hit boxes are so large. It's annoying that it keeps reverting to first person view on spawn.
I noticed that you tend to switch between rebel and empire forces each round (unless you are joining on someone), which means you can play a round on drop zone as a rebel to almost guarantee that you can then play walker assault as the empire. Thankfully either people are more aware, or they have tweaked the time the walkers are vulnerable to give the rebels a better chance.
I can't help feeling that once the rebels regularly have decent a wing pilots who can use their tow cables, the balance will have shifted completely towards them.
And some of those spawn points are so bad. If the empire get behind the rebels early, you can end up using their gun emplacements on their spawn points.
