Due to planes being ‘kill streak’ abilities in arcade, it’s easy to find complaints about players intentionally dying in them to secure kills, going back over ten years.
But now that the game has added ‘maneuver kills’ to detect when someone intentionally Js out or crashes to avoid giving another player credit, this seems to align with this arcade-specific issue. While I’d like to see the problem permanently fixed, it should be obvious after a full decade and a half that Gaijin has no intention of doing so.
Instead, I’d suggest something simple: when someone suicide dives you in an arcade plane, killing you with bombs/rockets/etc, you are awarded their kill, regardless of severe damage. In addition, you receive a minor SL payout, specific to arcade.
