You can test either of these elite specs out in the PvP lobby, as long as you own the expansions. In PvP, you can set elite specs before you've unlocked them in PvE, so you can try out the new weapons and traits there on training dummies or even on NPCs in the lobby, without actually needing to play PvP games. A handful of traits might have differences between PvE and PvP, but you should get the gist of it. Thanks I did not know that!!!
