Planes should have a time limit

One of the most infuriating things in BF5 is when one player racks up 50+ kills and has 0 deaths. Someone can take all the fun from the game by endlessly bombing you over and over and over, yet you have no chance to fight back. They’re simply too fast or gone before you can return fire with an appropriate weapon. This is especially annoying on maps with no Anti Air systems. 

I request that a player either has a points/kill cap after a certain number of kills or that a timer is introduced. One person using the plane also stops other players from using it, therefore not allowing other players to tune their skills with flying. 

this playing behaviour is on the very edge of being an exploit as it can make the game imbalanced. You may argue that being a good pilot and air superiority is key in war, however, when you have a level 500 zooming around simply XP farming for nothing whilst everyone else has to grind for progress. This isn’t a fair game.
