Interesting. In my experience, if more than one Guild gets to 133.3% the #1 spot goes to who got there first.
100%
sometimes guild have 133,3 BUT one pplayer has done 63/64 so in standing it shows 133,3 but it is not "full" 133,333333333
100% sure the first guild done 133,3 is first. And the others guild CAN NOT take their place.
THe factor deciding placements are:
1 - how much the guild have done (0%-133,3%)
2. How fast they have done it
This and only this.
The points you get from fighting etc, only matter for POTENTIAL the guild get at end.
In fact - if you are focused on potential it is better to keep losing at every encounter so you will get the WG points which accumulate for potential, but it does not affect the guild tournament
