Thing is, it's not really due to a player's skill, just how many skill points you have on that character. No more 'difficult' than just grinding to a higher level in MMORPGs, except, you would think a player is supposed to 'game' it given the agency we have with directional attacks/blocks, movements, animation timing, etc. Something like a competitive shooter where a player's skill matters more than the gun itself.
Tournaments are 'harder' now, no doubt. No longer can I win practically all rounds from the get go with no skill but that's more because I can't kill them, vs them killing me; if you know what I mean.
I lose because I'm trying different things to figure out what I'm supposed to do to win, because I don't have the patience to deal with the hit>block>hit>block for the next 5 minutes or 400 exchanges in this first 1v1 round; let alone the next couple rounds..
