Consider how long Rare have been working on this game, and the kind of barebones state it released in. It would be foolish to think that those same guys (except it's probably really a smaller live team) could then turn around and fill the game with all the content it desperately needs in a much shorter time window. If all they managed in 3 years was a couple of ships, some skeletons, and half a Kraken.....what are they really gonna be able to do in a few more months?
I don't think this has much to do with laziness at all. I'd say Rare bit off more than they could chew.
Yeah when I read the "new enemy type" I thought the same thing, as in... "surely they mean types, not singular" but then I would agree that in 3 years of development they managed to create a single AI which barely functions and can be pathed into area's for exploiting without any system such as "evading" like the mobs from WoW had 13-14 years ago when that game launched.
This might get content down the line in the same way No mans Sky did, but the first impressions are what makes or breaks a new IP and the first impressions of Sea of Thieves were so negative it would be very difficult to turn around gamers opinion on it down the line, especially when there are so many quality titles out this gen and coming out in the coming months, I'd be very shocked if this project manages to turn around into a success after the launch/review period it had.
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
