I've been playing Trinity for a while now, and while fun, there's one big problem all of my ships seem to have. For instance, say I have a few torpedo cruisers attempting to take down an enemy starbase. If I realize it'd be better to retreat, and tell the torpoedo cruisers to turn around and exit the gravity well (150-180 degrees AWAY from the starbase), what do the torpedo cruisers do? They charge directly into the starbase while attempting to turn, possibly killing them! Or, if my fleet is engaged with another fleet, and there are enemy mines in the gravity well, I make sure to direct my fleet to stay AWAY from the mines, and to attack the enemy fleet only up to the start of the minefield. Suppose I then want my ships to turn around and retreat, or to engage an enemy capital ship that just warped in on the other side of the gravity well. So, after I direct my ships to turn around, what do they do? Do they turn around? No, they charge forward with thrusters on full, blowing half the fleet to smithereens on the mines! Only after that have they managed to turn 90 degrees or so... but they're both crippled and much farther from their destination than they originally were.
In short: If I have ships attacking something in the South, and I order my ships to go back North, where do the ships go? They accelerate South, perhaps moving a fourth of the way over the gravity well before actually turning back North. If it's a capital ship, I'm lucky if it manages to get to the destination without traversing half of the gravity well in the opposite direction.
This sort of movement behavior is VERY nasty, and has cost me (and likely many others) quite a lot of ships, including many capital ships. If I want my repair cruisers to retreat, that obviously does NOT mean they should first go on a sightseeing tour through the enemy heavy cruiser front lines, or into the enemy starbase. It's as if the ships' captains equate a retreat order with a suicide order, and try to see just how much fire they can possibly draw before actually turning around and retreating.
I can only hope that such horrendously stupid movement behavior is a bug which is going to be fixed in the next few months or year.
Just thinking off of the top of my head, I think a very simple solution would be for ships to rotate a bit in the desired direction before putting the ship's thrusters on full, maybe 45 degrees or so, so the ships don't go charging off in the opposite direction you told them to go. Ships already do this sort of thing if they only have to move a small amount backwards (less than half the length of a tactical square) - why not simply make this the default behavior regardless of destination range?
