Someone explain to me how this...
...satisfies Boon's repeated claims and, indeed, one of the key selling points of the game (and supposed core design change that apparently makes MK11 its own beast, as distinct from just 'MKX.V: Make it Easier for Gore-Loving Kids Edition'), that players can
"customise their favourite characters the way THEY want to"...?
For, as far as I can see, not only is the system rendered a rather failed
in utero gimmick -- given, according to the video in the OP, it is restricted to vs. dumbot use only -- but, in light of how restrictive the "slot" system is going to be (the exampled case here means Scorpion will have to use up all his """customisation""" in order to have access to one, simple combo string), there will be little "variety" at all anyway.
If this is all borne out as fact, I can already confirm that I (and most others, I'd wager) would have much,
MUCH preferred either an 'Armageddon'-size roster, or even more fleshed out existing characters (more specials, Fatal Blows, Brutalities
etc.), in lieu of these, what look increasingly like pseudo "variations". You can colour me 'worried', now that this information has been revealed...
