Idunno about graphics being better, yes the tag is better considering that is what it's based around, the spamming is something you as a player need to work on preventing. Complaining about it won't make you better against it.
There are spammers in every game, but yeah Tekken is rough when it comes to that. Same with NRS's games. The second thing you should do when you learn Tekken is how to deal with Law, TKD & Capo spammers. The first thing is movement and spacing. The third thing are the stupidly long tag juggles.
