So, I read what competition got...news are not good. I think Devs are trying to kill this competition for overseason servers....
First: The World Olympiad takes place on Friday and Wednesday from 8 p.m. till 12 p.m. (4 hours) server time (registration is available till 11.40 p.m.).
It seems it will be onlyone GMT or It will be x2 competition(for each server GMT).
Second:
You can participate in 25 battles per week in total.The minimal amount of battles required to get the Hero/ Legend status is 25 for a cycle.
So from 10 to 25 battles but the important change is 1 battle have x3 rounds of 300 seconds.
Her comes the trick:
For each battle won you can get 10 marks, if you lose you get 4 marks.
At the end of month, depends of your result, you receive Olympiad points(lets say you are in first 25% and you get 55 olympiad points)
You can exchage your olympiad point for marks of battle(50 olympiad points=1 mark of battle).
Now, doing the math, you play 100 battles and lose 50%>>>700 marks+1 mark from oly points=701 marks.
Oh, the trick is all the prices for oly goods stay the same(Superior Giant's Codex - Mastery=600marks;Hero's Ring =2200 marks, etc).
So, in my eyes....finally they manage to nefert Olympiad.
The good thing is you dont need to do oly for exhalted quest.
