I have attempted many tactical FPs now and have only completed 2 out of the 10 that I have tried. Things seem to be just over the top difficult. Grouped with some lower gear people bolstered up and it's not like the space yard GF missions, but stuff that is really hard. Example, Manaan mission, the 2nd to the last boss. Dealing a ton of dmg, way too much for a group without a healer and just the little stations. Everyone is trying to kill the adds, who do a lot more dmg then the 3 click heals can save you from plus the lighting attack (Flow) which knocks you to half way.
Everyone is lower level then 65, obviously and just about everyone is dps. The heal items heal way to little and have a long wait time.
