SH III is far to easy Player V's Bots. The only time I break out in a sweat is - Sub V's Sub, Player V's Player.
In fact the predictability of the AI is the main reason SH will never make it to the big league, the repetiveness of the action makes SH the same as fishing - the art of waisting time. Adding a little spice to the mix is never a bad thing (mind u tho, I luv fishing

).
I would luv to skipper say a Cruiser or BB with DD's an DE's in escort (All player controled) and take on other surface units whilst I have to worry about some nutter in a Sub out there somewhere determind to put a dent in my day. Or bring a Convoy in and try to sink my opponents sub, take a TF and do a shore bombardment and maintain a defencive perimeter to keep the subs away while they try to sink me.
Diversity is the spice of life.
