...And life -- not just frivolous gaming -- will continue to feel that way ("taxing and downright prohibitive"), if one cannot or is (most likely) unwilling to create of new neural pathways ('connectomes'). Genuine disabilities (colour-blindness, physical handicaps, missing digits / limbs etc.) aside, any argument or complaint revolving around something being "too hard" or "inaccessible", is an effective argument against evolution.
Protesting for easier or more homogenised input command schemes in fighting games, is tantamount to boycotting one's running of a military obstacle course -- because it's "too hard" -- and then still expecting to be accepted into the armed services (i.e., for the threshold for entry into a the group, to condescend to one's sensibilities). To reconcile the analogy: If exampled military were to nevertheless accept someone unwilling to undertake their training regime (because it was "too hard"), it would clearly undermine the effectiveness of said military.
Just sayin' ¯\_(v_v)_/¯
