Ack and wirbles are a learned skill. Sure they can see you before you can see them.... unless they are sitting on the field, or are firing. I ran my numbers over the last year and have a 1.2 K/D vs wirbles and Im nothing special at dive bombing, but I have practiced at it. I can deack a small field all by my self. If you practice as a "team" 3 guys can deack a small field in one pass, use to do it all the time. These are LEARNED skills. There is no reason to have the game nutered to make it easy to do it, just PRACTICE!
Dar was changed to slow the number of NOE missions. There were a number of squads that used them as their ONLY mission and if it was spotted, they didnt fight, they bailed. Like those players that gamed the game and kept dar down for a country for hours on end THEY forced HTC into making a change.
This radar "test" maybe the next thing that HTC will be forced to do to help KEEP new players.
Not much else has changed since the "heyday", but the players and how they play the game. Bringing back the "old settings" will do nothing but bring back the old issues.
