BF Shield and GA rewards in NB: An Insurmountable Stat-Check on Fun

What is acceptable about giving a team that is 15-20 kills ahead the BF Shields/Guardian Angels award for an event that they couldn't possibly lose by virtue of their lead?

This was a huge problem in the first iteration of the mode, and here it is again.

My opinion is that these rewards, aside from simply being too powerful and serving mostly to snowball a team that is already winning even further, are inconsistent with the spirit of the mode. Every other reward can be negated or played around. You can't counterplay five people with giant shields or revives. It's an insurmountable stat-check.

Your only choice (especially when they're already ahead and can't fight them anyway) is to avoid the enemy Champions until these rewards expire, hope they make a mistake and get caught, or just feed them further to return as quickly as possible to them being 20 kills ahead without shields once again.

I think these rewards are problematic but they don't need to be removed. Rather, ffs, have the game CHECK the scoreboard before dolling these two rewards out.

Players should always have a reason to leave the fountain, especially in a fun mode.
