yeah, except no. Jin wasn't fine he lacked reliable options in many areas (AA, safe pressure finish, combo ender, abare, etc).
and he's gotten like 3 buffs, only like 2 of which is great (5C>5D, 214B knockdown) which doesn't change much since 5D can't be followed up with out meter.
oh and his 6A sucks worse now and his mixup is still balls.
