-1 enegry can not be replaced with the ease of taking poison needles, so yeah, I thing she was better then now.
Wrong. Jatai is a stronger and more formidable character for all poison affliction teams. She can now be used more efficiently for that. Sure, the drain was good for drain teams, but with all the drain characters we already have, this makes for a more awesome and unique character, thus, more awesome and unique teams.
Also Tadao's change makes him slightly better as a final resort, although I personally think that making his 1 strength attack piercing would make him better.
I think Ramen is much better now. Imagine an Akira Yuurin team with that, that would be pretty epic. Like:
Akira, Yuurin, Tadao.
I like these updates. >:3
