I suggest these...
1. Leadership:
The bigger differences between before and after are, the better it is to zeta.
(ex. Palp, JTR, JKR, Finn, KRU, Bastila)
—cf. examples of still great leaderships without zeta: Jyn CLS — These are not your high priority.
2. Unique and Special
Also zetas which make huge differences between before and after, like Raid Han, are great!!
“OR” what make some effects like leadership abilities, “when *** is alive” like that, are much more better.
CLS(Binds), R2-D2 or Traya are the representative examples.
IBAT: Could give a bonus TM
CA: Cleanses when dispels
NC: Adds more stats
Traya: Self-Cleansing
To “ALL” allies — This is the point.
