Just 22 story missions? Well I hope that isn't true or that some of those missions take a long time to complete and are really deep. On the topic of 6 strikes; judging from the one strike we got access to I am guessing they will all take some time to complete so 6 isn't too bad. I would have liked more than one raid but I am guessing that single raid takes a long time to complete and is hard to complete in general. The number of things to do is pretty good for a free-to-play. I would prefer to have to pay like 10 bucks every month in exchange for a completely shared world with different servers and more missions, strikes and raids but that is probably just my opinion around here.
