It would look worse if it hit, IMO. 3D fighting games should have accurate, 3D hit boxes.
Then they should redo the animations so it looks natural for mid ducking moves to get hit, because that shit is really fucking stupid when at least half of those moves also happen to be juggle starters.
Tekken 4 had some problems but it had some legitimately good ideas that people tend to sweep under the rug because the balance and pace was bad in the game.
They re-did the art style of the game and that also included the standard character design of many of the classics. Tekken 4 also introduced wall combos which later became a staple of the series (if they didn't try for it then we would still be stuck in T3 era infinite stages + no walls for additional strategy). Plus it had the balls to rework the game play of their god damn poster boy character.
The funny thing is that prior to Tekken 6, each Tekken game was actually very different from the previous one.
Tekken 3 was very different from Tekken 2. Tekken 4 was very different from Tekken 3/TTT1. Tekken 5 was very different from Tekken 4. However since Tekken 5 there hasn't been a considerable change in the series. Sure, Tekken 7 is a good upgrade from Tekken 6... if you completely ignore TTT2 and Tekken Revolution that is.
Tekken Tag 1 was just Tekken 3 with tag, just like Tekken Tag 2 is just Tekken 6 with tag.
Tekken 5 was a jump back to proper Tekken, because Tekken 4's gameplay was trash. It's not just balance issues, it's that they tried so many new things at once that they had no idea how fucked it was gonna be.
- Uneven floors caused grounded hits, along with a few standing moves, to become semi infinites,
- Removal of duck cancels from backdash, but not adding any pushback to moves made it a zero range fighting game that was almost all about coin toss offense.
- Pillars allowing ridiculous combos, some of which were full life.
In reality, applying the same reductive attitude that some people here are to it, Tekken 5 is really just Tekken 3 with walls added to a few stages.
I don't know why you imply that Tekken Tag 2 and Tekken Revolution are anything like Tekken 7. First of all, the only major mechanic that this build of Tekken 7 has from Tekken Revolution is the lack of floats for backrolls and the inclusion of backwalking. Second of all, every major mechanic from Tekken Tag 2 is gone outside of the bounce from floor breaks looking like the bounce that characters would get off of Tag Assaults. Lastly, Bound has been removed and replaced with a
slightly similar mechanic that has very different applications.
Top all of that off with the major gamechanging inclusions of armor moves and super moves, and this arguably becomes the biggest change to the Tekken series since the transition (Sans Tekken 4) from Tekken 2 to Tekken 3.
