How many Zeta's will Mr Grievous have?

2 zetas at minimum, because right now he has 4 abilities, 2 omegas. Could be another unique and thus another zeta

I don't expect him as a unit to be on par with any journey character, but I expect him to lead a seperatist droid meta that is equal to if not better than revan

His leader and unique abilities are both level 7 upgrades, so I think they will get zetas.

At least 2.....possibly 3

I can't see him getting 3. As far as I know, the only characters with 3 zetas are the 3 "Journey" characters. GG deserves to be better, and I'm looking forward to droids having their time to shine, but let's not get carried away here. This is not a character who should have 3 zetas.

I dunno, I kinda feel that I'm okay with every major faction having a triple zeta lead..

In Sep's it's either him or Dooku and Grievous has dual utility with droids.
