To play devil's advocate, of course, shallow water is only deadly when there's competent ASW present! During Operation Drumbeat, many of the kills by U-boats were in waters off the coast that were too shallow to even dive in, and yet no boats were lost.

That said, I don't expect SHIV to be a turkey shoot! It certainly shouldn't be easier than SHIII - and even though someone very rightly called SHIII an 'ace simulator', which will certainly expand to SHIV, I don't think you can count on getting away with impunity. A subsim shouldn't be murderous at every turn - I think it's always a matter of respecting your enemy and not making errors. It will be a fun game to play as long as it rewards good, cautious behaviour and punishes for mistakes and recklessness.
