Yeah, though; as I said when we talked at NH, I think, the learning curve didn't feel too steep for me since I know the TT game inside and out, but there really isn't much of a tutorial, no. (To see which weapons are destroyed, you essentially have to squint and look at the actual ship, unfortunately - I think adding that kind of info to the UI is something they're planning for the future.
And rest assured, the extremely annoying nature of Eldar opponents is simply an accurate representation of how they play on the tabletop, heh. Fortunately, the campaign is set up so that you don't have to win every game to win, so the occasional essentially-unwinnable "Eldar admiral flees immediately" or "Eldar transports swish by your picket line" mission isn't too onerous.
