I have to say I agree with the more tank less gank approach to balancing HAV's. I have limited use with the missile turrets, but one thing I could see would be instead of just an across the board reduction to dps of HAV turrets, maybe change the efficiency of the turrets depending on what is being shot at. Say infantry would have a 50% efficiency dealing 50% less damage per shot to them, but you could still have 100% efficiency against other vehicles and installations.

Not sure how much of a difference it could be, those are just some numbers off the top of my head. I have been a big blaster user, so that is my primary experience with HAV turrets. Just my 0.02 isk.

Edit: The efficiency could actually vary depending on the frame size of the infantry you are shooting at, so it would be very difficult to kill a moving scout while a waddling heavy would have a higher efficiency rating.

I believe what I was talking about has more to do with tracking speed for the scouts and heavy variety. Just throwing stuff out there, we all need to do some serious thinking cap talking if we want our HAV's to be more like tanks than wet paper bags.

Edit: Combine tracking speed variety between turrets of different calibers and efficiency rating and there might be something there, but it would need to be tested a lot.
