Yep, bottom line is WGT has enough to do before they can get around to playing tier police. That's why they should just add a bunch of RRs to the threshold for moving out of the lower ranks.
20 RRs to get to Amateur, another 30 to get to Pro, then 50 in each of Pro and Tour Pro. Make it so P and TP can't wager more than 10 and 20 credits (respectively) on anything (RGs, Blitz, Skins, MP), no premium tournaments in the lower tiers. Free weeklies and monthlies stay as-is.
The multis aren't going to grind out 150 rounds just to get (re)started. Real new players who like the game blow through that in no time...and have fun doing it.
This parallels the WD discussion in the VUSO thread. It's amazing how some people just have to "win" even if it means doing so a tier or two below where they belong, or are compelled to sport that 90% GIR and <2% three-putt percentage even if it means quitting games...even though we can all see who the chronic WDers are.
Hooray hollow success! Not.
