Changing ranks by doing nothing is completely normal. Rank is based on ELO (or Glicko, or whatever). You do not know your ELO. It's hidden, you can never see it (in some games you can, like in TF2:
). ELO is based on wins/losses using some complex formulas. Rank is based on ELO by dividing ALL players into ranks based on their RELATIVE ELOs. So the 1.7% of the players with the lowest ELO will be placed in Initiate II, the 0.5% of the players with the highest ELO will be in Eternus VI, et cetera (percentages are examples).
This means that your rank depends not just what
you are doing, but also what others are doing, and who you are matched with and against. If you keep winning against players with lower ELO than you, then you won't gain much ELO because you were
expected to win.
Now, according to Tracklock (
https://tracklock.gg/ranks ), Initiate II is actually currently the lowest rank, so there may indeed be something wrong for players who are consistently winning games yet still stuck there, maybe some boundary effect or incorrectly calculated ELO or something. Or maybe something about new players joining the game? No idea, we can't look under the hood.
