Personally, this is one of the reasons why I also miss the end-of-patrol teleport of SHIII.
I don't usually have a whole lot of time to play, so I am a big user of TC. But what I really hate is the return home, with torpedoes expended, and often with deck gun ammo low or out.
Since I have air-warning radar, and later surface radar, I'm going to go deep, slow and quiet at any hint of danger on the return to port. And it get's really, REALLY, boring going through the same old process - set speed to 9kn (unless I have lots of fuel left), hit TC to 4096 or so, drop out of TC for radar contact, dive deep, set speed to 2kn, hit TC again, wait a bit (or until night), surface, set speed to 9kn, hit TC - now repeat over and over and over again just to get back to port so I can refit and get back to actually doing something in the game.
When SHIII first came out, I actually docked my boat back home the first few times out (backing into the pen at Brest was interesting the first time). But after awhile, it just got boring, especially as I don't have hours and days to sit and play. So I use TC and teleport in SHIII, and TC in SHIV, but I'd also like the teleport option in SHIV.
It's not near enough of a flaw to make me stop playing it
But it seems an oversight on the part of the devs. It should have been there as an option. Nobody has to use it in SHIII, but it's there for those who want it.
