I have no doubt the testers are testing stuff for G16S2's major combat style change with its cooldowns and all. We could officially get the changes, we could not, or we get our own changes that the testers may be experimenting with. I don't know about anything else. I didn't get in the test server. Selected testers aren't even supposed to say anything about the server either (they have to do some agreement and such), so most likely there will be no mentioning of anything that is going on in there until we officially get the content.
