And I can't get enough of him! It is great to have the series protagonist character who is also great gameplay wise. Jin can pretty much do anything. He has great pokes, lots of safe strings, stance mix-up, evasions, parries.
If you can think of a certain way to play Tekken, I'm giving you 99% that Jin can do that. Defensive game with the focus on punishments? He has electric (not as strong as Kazuya's though), one of the game's safest parries and a stance for counters - ez. Offense? Nice 50/50s, above average damage, safe strings.
His only weakness is pretty much the lack of range. And what do you make of him?
