MM1DW2 was changed because it was too easy to defend/stall in the water passageways.
And having older maps revamped without much of a warning is what the people should expect while an expansion is being created.
It happened with Windman, it happened with Plantman, it happened with Shadowman, it happened with Cloudman, it happened with Waveman (v3a), it happened with Ringman, it happened with Sparkman, it happened with Yamatoman, it happened with MM1DW2, it happened with MM7DW4, etc.
Is this one map any different from all those?
* Wind Man is getting changed in the same version as Heat Man. It has the same problem of getting abruptly or unexpectedly changed.
* Shadow, Wave, and Ring Man were all forewarned.
* Spark Man was a minor change
* Issues were discussed with Cloud Man and MM7DW4 beforehand.
* When did Plant Man change layout?
Yamato Man was an abrupt change.
