Its a game. If the developers want to make a defense heavy game they will and they have. Trying to tie it to real life fighting just doesn't fall in line with the video gamey nature.
That's what I'm saying though, they clearly didn't land here intentionally. They wanted Tekken to be the MMA game with diverse fighting styles battling it out, but it hasn't really been like that since Tekken 3. They went along for the ride, but with every buff/nerf, it is incredibly obvious that is still what they really want.
- Although it was improved a bit in Tag 2, movement has been nerfed more often than not ever since Tag 1.
- They constantly improve poking damage.
- They add a ton of evasive moves, so unique offense can take the place of movement.
- They add throws that start juggles.
- There are far more + on hit lows than there used to be, so it's easier to mix up and maintain offense.
- They nerf the hell out of low parry so you don't get absolutely slaughtered (at least not as badly) for just going for a low poke.
- They added homing moves as absolute almost 100% anti sidestep/walk option. Yes, a lot of these moves tracked in past games, but the tracking was improved with the addition of the homing mechanic because these moves now auto realign instead of just having a good hitbox to chase you down or a built in dash input to help realign.
All of these changes point to them attempting to diversify viable playstyles in the game, yet one play style still rules all others to the point of making them obsolete at high level play. Bait whiff, and punish. Defense is just too damn strong in Tekken.
