One thing the ES could've done (examples incoming) was analyze which moves in lenshu3ng are broken (mostly contract knee openers/kicking openers)
then nerf those openers by making minor adjustments in mod maker, such as decreasing the foot sizes
another example would be runners in lenshu3ng; they could decrease the dojo size by a few numbers to "nerf runners"
heck, they could also add 100k winpoints to reward aggressive players in ABD because a lot of players lift
Not going to speak for ES and/or modmakers, but my impression has always been that despite asking for change, hardcore players actually take it very poorly. Each time mods are tweaked in any way that's not already commonly used by players, staff get shit for it and are asked to revert everything back - so it's very likely that ES just gave up at this point.
Fun mods/tourneys, on the other hand, provide more room for experiments - you add some weird gamerules that break the existing meta and require players to come up with something new, but you don't have to test the mod for months to make sure it's true to esports standards. Considering all our staff are volunteers, it makes sense nobody would want to spend their time arguing over how competitive the mod they're hosting their event in is.
