Any rule changes should also make consideration for new players who don't care or know about the history of SL and have other games they can choose to play. If another game gives a better sense of being in the battle, rather than ASL, because of an few odd rules then do you really want to cut off that opportunity to increase the player base.
ASL, IMO, has some features that won't appeal to many younger players, and by far the biggest of these--and the biggest barrier to entry for new players--is the great complexity and depth of the rules (a complexity and depth which I love BTW). IMO changing ≤ 1% of the rules isn't going to make the slightest bit of difference in that regard.
Other features also work against younger players getting interested in ASL . . .
--The war having ended 80 years ago. (When I was born, WW2 had ended only 17 years beforehand, while the ACW had ended 97 years beforehand--which meant I had much less interest in the latter, in large part due to the "ancientness" of it.) And most of the war movies on TV as I grew up were about WW2--that also helped.
--The ultilitarian [and perhaps dated] fonts and artwork. (Which I also don't wish to see changed: I prefer them to, say, the many-colored fonts and colored silhouettes on many of GMT's games.)
--The fact that it's not played on a cell phone with whiz-bang graphics and social media interaction.
--The now-dated "I-go, You-go" turn structure, and how every rule rests on the advantages (and disadvantages) of that structure.
--The large number of core modules one has to purchase.
And in the end when you try to make a product into something it isn't, you almost always fail attracting the new target while also alienating the old target.
OTOH a lot of things are "dumbed down" nowadays. Yet I think there're people out there who yearn for more. So instead of trying to streamline the complexity of ASL, maybe we should lean into it. Instead of telling new players, "There's pages and pages of rules you have to learn", you say, "Do you know a crew can have the tank shot out beneath them, hop out, grab a big house-blasting gun, fire it at the enemy at point blank range, only to turn them into screaming berserkers who charge out of the down-raining rubble and come at you in hand-to-hand combat!"
ASL: Not for Rule Wimps!
