I stop playing for 4 months. During that time I collected about 60 resource crates, and only 24 merc fleets. I know that not everyone will send me a merc and a crate, but usually I get one of each per day. There does not seem to be a pattern, and I do not have to do anything for the merc fleets to disappear, including logging in. If I don't use a merc fleet, it takes it from me.

Not really fussed about auto launching mercs, how many actually use these underpowered fleets now, they do need a big update however to make them consistent with the tech some high level players have.They're handy for the low levels, that is about all.
