It does happen a lot. You need to control 3 or more points to win the game. Champion kills do not count past a certain amount of points (100 ish?).

I've had 2 games where the enemy team lost with 1 point. I like late game champs

I cannot be certain if we controlled 3 or they did at the point they dropped to 1. However, I am certain that I was killing minions at that point and it was not affecting their score whatsoever As in, it should have dropped faster.

Past that 100ish threshold, the ONLY way to decrease their score is via points. Minion and champion kills will not make the enemy lose points past this threshold. You probably lost a crucial point just in the nick of time, and their late game champs prevented you from being able to take anything back. Like they said to you: it happens all the time.

Okay, I suppose I haven't made this clear enough. In the grand sense of, people win the lottery "all the time" and football teams come back from 40-0 scores in the last half to win the game "all the time", I'm sure this would be considered a regular event. So here's what's bothering me:

People do not see other people win the lottery all the time. The people are geographically in different locations. People win contests "all the time" but I don't know a great deal of people who do, not even with the huge online communities I'm a part of.

What you're positing here, is that a team, who was getting CRUSHED by over 300 points, was somehow mysteriously able to rally EXACTLY when their score hit 1 point, was able to hold that 1 point until the other team, which had been ANNIHILATING them, was down from 300 to 0, without the likely benefit of any communication other than typing.

Mathematically, the odds are enormous, that JUST as it ticks down to 1, this sudden turn around happens. This is on top of human nature, ESPECIALLY in this game, which is to give up when you are getting such a job done on you. And this rally all happened... because of some carries? And this is a "common event", which states that this incredibly unlikely scenario somehow happens on such a regular basis that people don't even consider it rare?

This would indicate one of two things really:

1: There is a "pause bug" in the Dominion system that makes that last tiny digit last longer so teams have a rally point. This could be true, but considering I've watched my team drop from 20 to 0 in about 20 seconds, seem unlikely.

2: That whatever was done is done so regularly as to entirely strip away the absurd statistical probability of it and make it a common event. Remember there is a difference here, between something that CAN happen and something that DOES happen, and often.

Thus, either way, it deserves to be looked into. If I came up to you and said that I've won the lottery jackpot, twice, and then proved it, you would be seriously questioning the validity and the sanctity of that lottery system. This is a similar situation. If this happens "often" then there is the possibility of an exploitable bug. It is possible that the system is not working as intended (I'm sure that comebacks are possible. But for it to happen that dramatically, that regularly? Is indicative of a problem). For all I know, it could be that besides three or four "groups", no one else has seen it happen and that probability was just overabundant and the other team was actually not saying that KIND of comeback happens "all the time" but some KIND of comeback.

However, the manner is suspicious. It wasn't WOW that was such an amazing comeback, woot! It was as if they already knew it would happen. Isn't that odd? I think it is.

You are making **** up. Do you even know how the mode works?

maybe they were feeding off the archangel's sona with no hp

Don't say "GG" until it's really over, it makes your team stop and relax, and then you lose important objectives.

Mathematically impossible? All the enemy team has to do to win, regardless of the nexus health, is hold more points than you. From the wiki:

Dominon is a capture-and-hold game mode where two teams of five players compete on the Crystal Scar Field of Justice to destroy the enemy nexus. The nexus is untargetable and has 500 life points. These life points can only be diminished by controlling more Capture points than the enemy team: the more points you control, the faster life points are lost by the enmy nexus. When both teams have the same amount of capture points, neither nexus will be damaged. Killing an enemy champion also reduces their nexus' HP by 2. The nexus' HP will stop depleting life by champion kills once it reaches 125 HP to avoid victory by "ninja capping" (Capturing points just to deplete the health of the nexus instantly) or by "winning kill" (Associating victory by finishing off enemy champions)
