If we had the higher 88 gear speed, we could lead fighters like using a 5incher. That would probably be a subscription canceler tipping point for many who manage most of their kills taking advantage of fields. I understand protecting CV. Fields have wirbles and fighters. And at some point, if the defense didn't happen, it didn't happen and the game rolls on.
I know what I can already do with an 88 or a 37mm. Give me a higher traverse speed with an 88, it will be like cheating. You will also end up with the same group of 5 incher couch potatoes, waiting at every field you make the radar flash screwing your pooch. They will have an incentive to get good at longer ranges to keep you from killing their position to get at the stupider ones who will fill their kill string. Just like they do from CV groups.
The 88's are an unintended consequence double edged sword.
Instead of asking for a faster traverse speed with the fixed ones. Ask for a mobile one with the faster speed. That will make them a bigger juicier target on the airfield including attacker points for GV destruction. Limit them to the up\down of the VH and vehicle supplies deliveries. While giving you the faster speed at the cost of a successful deployment, resupply chain, and successful towering out. No perk cost needed.
