We just received Kain's 5* upgrade, which is really nice, and made him one of the strongest physical attackers (not counting Lighting and the other 6*, of course).

After doing the Giant of Babel PRO (I won't even try ELT), I awakened and leveled him up to 80, and so far I'm really, really satisfied with his damage output. But alas, he still hasn't received a 6* upgrade in Japan, and most likely never will.

He has however received his enhancements, recently. His Dragoon Spirit got upgraded to 150% Jump damage bonus (for a total of 250%), and his Dragon Dive got a massive boost to its damage, from x2.1 to x3.1, leading to a massive x10.85 total damage, or x5.42 damage per turn, which is unbelievably high for our current standards in GL.

So, I was wondering, in the JP meta, can he still be useful with these enhancements, at least for the players who haven't got the top tier physical/magical 6* attackers? Or is he completely outclassed by any 6* damage dealer?
