I do not have 2.5 hours to complete a mission on a game. I play for about 1 to MAYBE 2 hours at a time, maybe twice a week or so. I don't have that kind of time. So, it is very aggravating to take the time and get a team only to go in and have people fly around like dummies while the probes go right into the center gate. I do not feel that any game (MMO or not) should take around 2.5 hours to complete one mission. At the end of the day, you shut your computer down and you go back into a real world where those hours are precious.
It seems your main complaint is the length of time it takes to complete. As Gozer said here (he made KA so you may want to remove your threatening language from the first post), the new versions will be split between space and ground and be no more than 30 minutes each. This should go a long ways to allowing you to enjoy this team-based content when you have only an hour or two to play at any given time.
Edit: These are tentatively scheduled to go live September 22.
