And not just mindless bags of HP and unavoidable, or nearly so, one-shot kills.
With the Tholians serving as the third version of the 'secondary' bad guys, there's been some rumors of Tholian STFs to go with the Tholian Rep in May. So if there are, I really do hope they are truly challenging and actually provide some real effort and skill to complete.
As it stands now, outside of PvP, the only real challenging PvE things to do is: Hive (space and ground on elite), and No-Win Scenario.
So I really do hope it's worth doing these if they happen, because the game could use some more real challenging stuff to do, especially with all the people coming into the game new, and returning to the game from having quit.
