Nexus Blitz "underdog" advantages

After playing a few rounds of this, I feel that while the location handicaps they give for events are good to prevent a total snowball, it is unfair to start them when the lead is very small. I have had scores like 6/5 spawning the fire ring around the enemy turret. This is totally unfair for our team because that 1 kill did not give us that big an advantage to even think of towerdiving. Even at 10/6 I would still hesitate at a 5v5 tower dive that early in the game.

While there should be some anti-snowball mechanics in place (note: some, I still like it ending quickly), this is overdoing it because it is literally swinging the advantage to the enemy, not just letting them catch up, which feels totally unrewarding to play well. At this rate, there may be a strat of intentionally feeding right before an event just to get that advantage, because of those broken rewards.

Remove that mechanic until the gold/takedown difference is significantly bigger, not just 1 kill down.
