If you are a common legend grinder, or even rank 5 grinder which gives a "x9" star boost at this point, the climb back up to rank 10 (now known as diamond) is fairly trivial. I'm back up to gold 1 with only 6 or 7 wins, and if patterns follow, platinum won't be much slower.
I enjoy the idea of starting everyone off at the same starting line each season, but I suppose the advantages given to high finishing players were necessary. Having to slog through 50 ranks one star at a time might be a little much to ask for folks who want to compete for high legend and such.
In any case, I've been away from the game for a few months, but with the announcement that the HCT will be online-only for the near future, AND invites going to the top 16 ladder finishers, you will see me ruthlessly grinding this month. I miss the tournament days of Magic: the Gathering, and decided this is the year.
Hope all are well and healthy.
