While trying to do STFs with our fleet, we had a huge amount of problems being able to play as a group.
First, we noticed that you can only pick RA or VA level STFs one at a time now and not have both in your mission log. This causes issues with group members not being able to join together because one has the RA and someone else has VA. Then, if you try to drop the mission and get the other you end up with the 20+ hour cooldown!
Second, you used to be able to pull the group members with you into a STF (at times, we do not care if we get any credit for the mission, we just want to help out a fleet member by filling in an empty spot and have fun). This again is now gone. Sometimes, members are in the middle or end of an STF and just needs help finishing, now you can't. Everyone has to have the same mission and start from the same spots.
We started out doing Infected, the gate got bugged at the beginning (a probe got stuck in it and we could not destroy it). A few didn't want to start again, so we decided to do the Cure; nope, because of the afore mentioned issues. On to Khitomer Accord; nope, a few of the new VA's didn't do Cure yet.
This caused so many problems, we ended up doing Terradome (which we did not relish because of the problems and time it takes). But, it was the only STF that 5 members in the fleet had available as a new mission that were able to group together. And, you guessed it, the end boss fight bugged and we could not complete it anyway. By this time, everyone just did not want to go back and start from the "Where's Sulu?" part after all that work. In the end, the great evening we had planed to do STFs ended up in none.
So, Devs: Can you please put grouping back the way it was? This is just discouraging even more group play that STO already has a negative stigma with.
