Figured I might as well throw my thoughts in along with everyone else.......
#1--I wish for a bridge/helm on the CV fleets, for emergency evasive maneuvering when the fleet is under attack. Dunno how HT would do it, but I was thinking either the "A" and "S" keys to turn, or mappable keys. A rudder position indicator along with a compass to show your heading. Control of the fleets would only be possible for a player on board the ship, and would supersede a higher ranked player elsewhere on the map taking over control as long as the "Captain" was on the bridge. After evasive maneuvers were completed, give the option of "Return to previous course" or "Plot new course".
#2--I wish for flight operations to be automatically suspended during above evasive maneuvers. Planes would be "locked" in place while the ship was turning and trying to evade.
#3--I wish for self destructing AA shells on the USN 40mm Bofors guns on the ships. Okay, this one should be at the bottom of the list, but I like the idea.
#4--I wish for more GV visual effects: tracks on the ground, dust trails over dry ground, the smoke and dust from the blast of their main guns. Like the aircraft contrails, my understanding is that they would or might cause a frame rate hit on some player systems. Possibly limits the tracks to one mile(?), and last no more than 2 or 3 minutes then they fade away (almost like aircraft contrails that fade away with time).
#5--I mentioned it before in other threads, so not gonna repeat the wall of text again.....I wish for clear defensive fields of fire for around bases. Clear all trees and brush around the base perimeter for half a mile to a mile. Site the weapons closer to or on the base perimeters, not behind hangars and barracks and such.
#6--I wish that, if and when #4 and #5 and able to be implemented, eliminate the GV dar. No need for it at that point. Just my opinion, but right now, unless our GV's are using mag-lev technology, they should leave some sign of their passage along the ground. In the interest of realism, I think it would be a welcome addition.
