We understand that losing elo from dodging does not make sense.
We asked ourselves the question “how is dodging affect one’s skill level”, and we
reached the same conclusion that dodging will not make a player better or worse
in terms of their skill level. So, a change has been proposed by game design, and
it has been implemented by Riot engineering. In the new implementation: ranked
dodge will not cause any elo loss, instead some other form of discouragement
has been added. This change should be released within a month.
