WoW, well be longer than I thought to get to cruiser, my guess was way off, having spent the 1 day to get frigate to 3, I thought to get frigate 4 I'd need 2 days, as up until then everything seemed to double in time. Nope, 5 days to learn frigate 4 !!
So I'm gonna get my learning skills up a little bit more first and whatever stat it is that the frigate skill uses then try again, which I think is perception.
Now I guess I should see if having Frigate 3 means I can get a nicer frigate even though I only just brought a new frigate yesterday morning !
