Because the community deemed tag as broken. and chose 1v1 instead. I dunno why they don't atleast try it out as a side event at grass roots scenes. are there a few infinites? Yea, but you have a breaker, and you can stop most infinites by making them break as well. Kind of like fishing for combos to make quan chi break.
I'm trying to get better with the Original 7 in Tag Mode (Sub-Zero, Scorpion, Kano, Sonya, Liu Kang, Raiden & Johnny Cage).
If anyone has some killer tag combos featuring the OG 7 in Tag (i.e Raiden & Liu Kang, Sub & Scorp etc., etc., etc.), it would be greatly appreciated, and (as always) I'll update the OP and give you credit for it where credit is due.
