Here's a tip for people who want to climb easily. Wait a month. The system is inflationary (it hands out more stars than it takes away) so everyone will climb up the ranks eventually. Once that happens, Gold will be like bronze and Diamond will be like Silver, so it will be easier to win. Enjoy your free Crystal ranks.

For people who want rank to mean something, sorry. It only matters for the first few weeks.

Currently the system serves no one well. It makes casual non-PvP players think they deserve to climb like it's a mount they can farm for, but ultimately just frustrates them because losing is part of the process. For competitive PvP players, it's only legit for a short while at the start of each season (debatably).

I hope the matchmaking doesn't go to shit half way into the season, but that's a possibility too. Matches have seemed reasonably close (with exceptions of course) above Gold, but as more people climb up, it might get more and more variable in the upper ranks.
