You completely miss the point of what you reported lol. Thats 100% intentional and its skill placing a good beacon and being able to flank / instant respawn in a good spot. But what you completely missed is a serious BUG unlike the 'bug' you are reporting.
When someone does respawn on his beacon in these game modes he gets NO DEATH. This is the major issue... not a player being smart in his beacon placement and the punishment of the enemy team not being able to spot it....
You're absolutely right about the "no death" bug, that's a massive issue that definitely needs fixing. I hadn't even considered that, and it makes the situation even worse.
However, my post was focused on a separate, but related, game design issue: the ability to instantly redeploy the beacon after an instant respawn. The problem isn't the beacon itself, but the lack of a cooldown in this specific mode. This creates an endless spam loop that counter-play ("just find it") can't solve if it's replaced immediately.
I think both of these issues need to be addressed to make the mode balanced.
