Thank you for all the comments.
I sense that the sentiment when this league was established is that much like in MLB, you choose your stadium and then you live in it. However, Strat owners don't get to decide things in the MLB world, such as when walls are moved, or when a new stadium is built.
Since it is reasonable to expect a stadium to stay at least somewhat consistent, it seems fair that owners in stadiums with significant, franchise-altering Strat changes from one year to the next get a chance to 'relocate,' while smaller Strat stadium changes should continue to be something owners adapt to.
I am going to recommend a rule change for severe year-to-year stadium changes only.
In the D2D league, there is a rule for severe changes that looks like this:
If the BP effects change by +/-6 in one category or by +/-15 in all four categories combined the owner may change stadiums after the bottom teams have made their selection.I believe these are fair criteria for determining a severe change.
That would mean for this year, teams in the following stadiums could opt to change:
Rogers Centre (Tor) - BPS-R changed by 7, Total of changes = 19
Camden Yards (Bal) - BPS-R changed by 10, BPHR-L changed by 14, BPHR-R changed by 14, Total of changes = 39
Nationals Park (Was) - BPS-L changed by 9, BPS-R changed by 6, Total of changes = 19
Marlins Park (Mia) - BPS-L changed by 7
Currently, the relevant stadium rules read:
3) Stadiums are unique and belong to each owner for the duration of the league. There will be no annual or seasonal draft of new stadiums, so choose your stadium wisely.
4) New owners may select a new stadium from the list of available stadiums if desired. If opting for a new stadium, new owners may not trade that stadium in their first year of play.
My recommended
changes are:
3) Stadiums are unique and belong to each owner for the duration of the league, except
a) if the BP effects change by +/-6 in one category or by +/-15 in all four categories combined, the owner may request to change stadiums. Eligible owners wishing to change stadiums must state their intentions within 1 week after the new set becomes available for play online. If more than one eligible owner elects to change stadiums, a stadium draft will be held promptly. The ballpark draft order will be the same as the Free Agent draft order with no lottery adjustments.
b) If a new owner joins mid-year, the new owner must continue to play out the Strat year in the stadium associated with the team. However, new owners are eligible to participate in the stadium draft at their first opportunity.
I will leave this matter open for comment for another day or two before posting a formal request for vote/check-in.
