What are they hiding?
Last time they were hiding trait lines and other unannounced content. They are hiding things like the specialization names which they accidentally didn’t hide for the elementalist and wound up revealing the name Tempest.
So they were just hiding things like that again so we don’t see spec names before they are officially revealed.
That the new way Thieves will have to get into stealth. In order to avoid all of those targetted reveals used by Engies as example one will have to put their hand over the screen to hide the thief. There a few bugs to work out like “How are we going to make sure the Engineer puts his hand over the thief on his screen at home so he can not see him anymore”
SR is to be replaced by the “peek-a-boo Blankie” skill.
