I am not a huge fan of the carrier ack system, there are several aspects that I thank could be improved.
However, I also think most (not all) of the complaints about it, are overly dramatic "woe is me" and lack any real points for discussion.
Here are some real points to discuss (and/or lobby for change) or just to think about. They are not all historically accurate but are focused on an attempt to improve gameplay.
1.) Puffy ack should NEVER be able to shoot around mountains. There has to be a reasonable way to run some sort of collision detection, maybe not for every shell but something will be better than nothing. Perhaps just a check to the bottom corners of the box once every five seconds or so?
2.) There are 26 five inch guns that make up the carrier puffy ack barrage, if a shell randomly passes you outside the proximity range you never know it was there. So it is impossible to say from the players end that you were hit by the first round. Think about it, at any one time there could be a maximum of 26 shells within the box around the closest plane that's a lot of lead with proximity fuses in a relatively small airspace.
3.) The current ack system has no way of determining who's really the biggest threat to the ships. If you're chasing/furballing a guy back near his CV at 3001 feet and 5k out from the ship, and a set of buffs is inbound at 10,000 feet and 7k out guess who is going to get targeted? I think the pufy ack should run some sort of friendly proximity check to the target it see if the target is possibly being fought by a friendly if so then it should select the next farther target and repeat the process. If there is no friendly within 1.5k the the ack should fire at the target.
4.) As I understand the current system, the ack only fires at one target at a time. I think that the ack system should run 2 boxes if there are multiple targets, if it's possible. I suspect it may not be feasible due to performance issues but at least it should be discussed. This would cut in half the number of shells within the box of any one target (provided you're not the only one) and slightly improve your chances of survival.
Dale and the rest of the crew at HTC seem very willing to work on things if you discuss them in a rational manner. So if you really want to see a change let's dial back the drama and focus on specific points.
