Would you like this Tourney, and would you play in it?

A smart pro be like, hey anyone wanna team up, we will win if you join me. Smart smelly no life scrub would be honored for this and team up. Awesome pro and no life scrub both make it through. True story.

Then don't have a FFA round.

Why don't you do something like this? https://exodusesports.com/tournament/cloak-danger/

Yes. That's what you get if you "fix" the "problem" you highlighted.

You don't need to have dynamic alliances thou, just an example of an ffa tourney and I think people atm might be more interested in that than in another 1v1 tourney.

I like that idea

That means no challonge though. Maybe put the one life into the Bo3 round rather than a double elimination?

make the players capped to 4 per ffa.
each player in that ffa gets lives to use during the elimination tournament based on how they did in the FFA.

1st place ffa. gets extra 3 lives.
2nd gets +2 lives.
3rd gets +1 lives.
and 4th gets no extra lives.

this makes it so if you die in the ffa first you cannot lose a single game in the elimination tournament. you win your ffa you can lose 3 games over the tournament before your out. do it with standard 1v1 single elimination style brakets. but keep track of lives left for each player. so if player A and B face off in round 1, Player A has 2 lives and B has no extra lives. Then B has to beat player A 3 times without droping a game. Player A only needs to beat B once to move on to round 2 with whatever lives he has left. if you do brackets properly there should not be to people with 3 extra lives facing one another tell quarters or semi's.

Could also make it in FFA that
1st gets 2 lives extra.
2/3 get 1 extra life.
and 4th gets 0 extra.

also adding in that a win in the elimination rounds gives you 1 extra life. so if you get 4th in ffa and go undefeated in elimination rounds. after 4 rounds and getting to the finals you could have 4 extra lives to face an opponent who might have got 1st in an ffa but dropped 2 lives getting to the final and only has 4 lives like you. making it a best of 9. which is a bit much but would be probably near a bo3 tournament in amount to of games from start to finish.

I like the concept, however if this was the plan we'd have to limit the maximum obtainable number of lives to 2 (so no games requires more than a BO3).

Btw Gandalfs idea doesn't require anything special for brackets- he's saying if a player has '2 lives' going into round 1, their opponent has to defeat them 3 times to get past them. If the player they are facing only has 1 life, they only have to win two games- kinda of like a tie breaker in tennis. I like the idea but may prove difficult to track as number of games each round will depend on previous performance. Also games could go on for a long time (like a tennis tie break) if one player wins, then looses next effectively resetting the score back to even again.

I don't know why everyone don't like this idea. I think it's great idea (I doubt if i saw it somewhere...)
This is how I understand it:
First round is to sieve veterans and weaker players so they can play with others that are similar in skill level.
Next we have 1v1 battles both veterans and weaker players on the end winners from both categories fight each other.

I want to play in it too

The reason you don't see this style of tournament is because that is generally not the outcome in the FFA bracket. Better players will not necessarily beat the worse players in an FFA. It may be more fun but it is a lot more random.

Though I still like the idea.

It isn't that good like first idea but still better than random single-elimination tournament.
