whats the most amount of games a user has played with a %100 win percentage?

Probably 1 or 2 as it is pretty much impossIble to be new and play 5 games and not lose at least one

When i start my main i make 20 w/o lose any

there are also ragequiters that farm wins and just /spec or leave when theyre about to lose, which makes it technically impossible for them to lose, but nobody likes a rage quitter.... and thats why win percentage isnt very accurate.

Yea that rage quitting technique is very common on this game and very annoying, I really think they should develop an anti-ragequitting system on this game. They also use this technique to win tourneys now, since the auto re-entering system has been put in place, players have been disconnecting there router when losing then re-connects to re-enter the tourney after lockdown. Also alot of the players that are well ranked also did some extreme farming. Example: Global Elo Rating: from rank 1-10, the players have all farmed.

Why doesn't the player that stood and fought, win that round and the player the ran away.....well, lose!

Your winning percentage wont be affected if you opponent leaves a match. The only thing thats happening if that occurs is that both you and your opponent will get 1+ Qi. And yea, there are literally no veteran TB players with a 100% winning percentage.

If someone skilled was to make an alt, then they could probably go atleast twenty or thirty games without losing a match.

Not exactly as example a black belt that have a good judo move just need to enter in a bginner server and can win a lot of matches w/o lose.

Well If I made a new account now and played on a beginner server, I guarantee I could win 20/20 games. It's not anything to be proud of, it's just the way it is.
