donsprintr: Disagreed anyone ... ???
Always ready to step up to the plate to do that. I believe 4 tiers are enough. The mistake probably was, that it used to be too easy (before August or so) to advance to the Master tier, and the mistake continues to be that it's possible to manipulate one's average score (by quitting every bad round) and so advance to the Master tier before one has the necessary skills. This could perhaps be resolved by WGT by redefining the Master tier; this game is only at the Beta stage, after all.
I'm afraid that setting up an additional tier might lead to excessive fragmentation and segregation of this site's users. And in addition to the dozens of repetitive forum threads asking "What does it take to get to the Master tier?", we'd also get dozens more threads asking, "What does it take to get to the Legend tier?", month after month. There would be no end to it.
