I played the Khitomer Accord Ground Elite STF under the new rules...
It is by no means as bad as everyone was thinking.
The respawn timer isn't much of an issue when people rez you (which they should do anyway since it takes longer to run all the way back...)
And the Optional timer is enough to complete it. Played it twice, completed it twice (one time with 1 second left on the clock, how very Galaxy Quest of us).
It's pretty much like Infected and Cure now... a random noob group won't make it, but a group that knows what it's doing shouldn't have much of a problem.
