You might have memories from the past. This was a thing over one year ago; it drove faster the more players were hugging it.
Closing because this thread is very old.
Rewarding players for being bad at the game shouldn't be a thing.
I wouldn't describe Sparks weak or even useless. Remember she can still poke and revive from a great distance, all she needs to do for that is peek out for a brief moment. You didn't finish this one player for whatever reason? Well, bad luck for you, he's back up on the field in the blink of an eye. The pressure this constant threat establishes is enormous, albeit you are required to have quick and precise aim. It's an ambitious challenge to get rid of her as well, the instantaneously healing medpacks she is given access to keep her afloat and allow her to make a quick escape with the addition of her movement speed. Guardian doesn't come close to that to be fair.
I can comprehend your sadness but to be honest snipers were beyond broken and a nerf was long overdue.
