Does not want you change rules of challenges?

Question

Really Challenges rules are not good!
If i play with level 11 learner and if match is draw then i get only 5xp if i loss then they cut 15-30 xp to playing with level 1-16.
It's not fare.
If you also disagree with this rule then please comment what you really want?

Answer 1

The XPs you gain/lose are unique to each match. Calculations take the opponents' levels into account. We use a modified version of the Elo rating system to calculate the points for each won/lost challenge. You can learn more about the Elo rating system here: https://en.wikipedia.org/wiki/Elo_rating_system
