Taking years to finish a subplot in a story line may well reflect real life but as this is a game a story line should start and finish within weeks.
MA may have decided Ending the robot invasion was a good idea but they missed a chance to have a final big onslaught by them and to have us defeating them as the end after a week or so then give us the beret as a reward for defending Calypso, instead we got the beret and a note to say it was all over.
Single day events although nice for some are a waste of time especially if they're announced on the same day, I'm thinking the RX unit events the first was to give away the new explosive weapons, the second as an alternative when the second landgrab got cancelled at short notice and the last one seemed to be either someone in the office got bored or they thought they had better do something to show they're interested in us as they hadn't done anything else for a couple of months.
The defining characteristic of the note events was that you could take part without spending a single pec where as almost all other events seem to involve the requirement to spend huge amounts on ammo.
