I really like the rule changes. For a smaller area like ours(Birmingham, Alabama) it will make our league seasons worth more points. With some changes to our launch party formats, those will likely be worth more points as well. I also like the idea that a single location will not be limited to one "annual tournament".
I have no problem with pump and dumps whatsoever. Do not forget that there is a certain amount of luck in pinball regardless of skill level. With a larger number of games played, the cream will always rise to the top. If you have a "one and done" format, a highly skilled player can easily finish near the bottom of the results. I know, I've done this many times at our launch parties!
