Extreme is shit. It's why you had to nuke with aoes in WT before Broly. Broly has Colossal on his aoe super which is less than Extreme at sa10. Though his passive makes up for that and when he makes it to sa20 it's basically Supreme multiplier.
Nah disagree, changing any random character from extreme to supreme only adds like ~10k damage.
It only makes a bigger difference if the character has a bunch of atk% links or passive you can take advantage of.
Like if we take ssj2 gt goku as an example with double 70% leads:
supreme no passive sa1/sa10
66k - 115k
Supreme passive sa1/sa10
91k - 157k
extreme no passive sa1/sa10
58k - 95k
extreme passive sa1/sa10
80k - 130k
At SA1 the difference would only be 8k! if he didn't have his passive for the attack boost. I don't understand how a difference of 8k suddenly makes extreme "shit"
And with his passive the difference barely reaches 27k damage at SA10.
So even though str arale only has extreme, she also has a very nice 70% atk boost, which will make her do more damage than units that have supreme, but no strong attack boost passive.
