But Cell was shown to be able to remain perfect without the androids.
Plus the problem here is more that you can't really ever use 17 and 18 in a tag team together.
18's support is 17's barrier I read somewhere. (either that or they gave her a barrier too)
So if you play ToP 17 with 18, and you call her, you'd get another 17 ? That's a disaster they won't even dare to fix so we're stuck with this garbage.
They'll give us a DLC costume and call it a day.
Since the character is forever unsalvageable, I wonder if they'd maybe consider swapping 17 and 18 with the ToP costumes of both.
Like Z version 18 is leader, Super version, 17 is leader. Would still require some work obviously but heh.
You will be able to have Gohan summon Gohan, and have multiple Vegetas and Gokus on one team. 17 would be just fine as an individual character.
