Yeah

That's one of the idea that comes along with the point system

that's how some tournaments are planned on who fights who.

for a round of 64, 1 vs. 64 , 2 vs. 63 etc.

But the more complicated part is the placement of each match. (because the 2nd seed shouldn't fight the first seed early in the tournament)

Like putting them into 4 seperate groups. like
1,5,9,13 etc. for Group A
2,6,10,14 etc. for Group B
3,7,11,15 etc. for Group C
4,8,12,16 etc. for Group D

winner of each group will be fighting in the semis to the finals etc.

And since this is for the top 64( or 32) we can call it the " Champion's Tournament " 

Dunno if it'll help... but i have an idea on how to make points...

how about doing it like the style of tennis??

each battle wins gives you points, like 10 points per win.
So highest person points will be seed one, and so on.

Also, for a tournament,
we can schedule a top 128 or just 64 seeded person

Tournaments will also have points... example:
64 -> 32 : winners will get +20 points
32 -> 16 : winners will get +30 points
16 -> 8 : winners will get +50 points
8 -> 4 : winners will get +70 points
4 -> 2 : winners will get +90 points
2 -> champion : champion will get +100 points

therefore, champion will get 360 points

but... there's also a catch:
Seeded will have an increased point level, like if I defeat the seeded 1 person, i will get instead of just 10, maybe 50 points

its just an idea...
