A player standing on top of an allied Recon drone is able to use the sledgehammer basic attack to "launch" the drone (and by extension, themselves) into the air/clip into geometry. This can be repeated until someone is high enough to deploy their parachute, at which point they land on a building that is meant to be inaccessible. Once up there, a spawn beacon can be deployed and squad members can spawn on them. This makes defending some objectives IMPOSSIBLE, as some of these buildings are considered "the objective" and teams are able to contest them without being in any line of fire.
This is most egregious on game modes like breakthrough or rush, but this exploit is being used in EVERY GAME MODE on EVERY MAP and is making the game genuinely unplayable. There are some maps and modes where a player has absolutely zero chance, as spawning in your own HQ could put you in one of these teams' line of sight.
Worst of all is the seemingly shameless, callous attitudes the bug abusers seems to have about using it, as if they can't imagine a world where this kind of behavior will be be punished.
I obviously am not a dev, but anyone abusing this bug should be banned for some period of time (if not indefinitely), INCLUDING players that are spawning on their squad. “When you access or use an EA Service, you agree that you will not … Use or distribute unauthorized software programs or tools (such as “auto”, “macro”, hack or cheat software), or use exploits, bugs or problems in an EA Service to gain unfair advantage". This is a direct quote from the TOS that I abide by, and I'm being punished for it because these players are allowed to log in every day.
Unless you want your game to be known as a haven for cheaters and bug abusers, you need to fix THIS ISSUE immediately, AND punish the people who took advantage of it.
