I'm currently in Gold II, so it's looking like I can climb about one rank a day.
Disappointing, as I have seen that there is in fact someone who has broken out of Gold into the next rank (I got matched with them), meaning my dream of being in the top tft players on Oceania is pretty much dead.
But I still feel that I can climb if I keep at it.
I devoted like 7-9 hours to it today.
I'm clearly having fun trying. So if I can climb one rank a day and I'm not getting burned out (and it doesn't seem like I am). Then I can get pretty dang far!
