OP, I must be stupid, because I don't see conflicting information here.
Forum post: tier 1 requires Marquees 1-5 (5 of 6, excluding KX Droid) at 4 stars, including Kleya at EL 45.
In-game newsletter: tier 1 requires the first 5 Marquees at 4 stars, including Dedra at EL 45.
Explain to me which goalpost moved. Did you assume tier 1 would only require Kleya? Or only Rebels? And you think that requiring Dedra at a certain EL contradicts this?
You silly goose.
Glad you admited yourself and didn't need anyone else to point it out.
Maul's journey to unlock 4 star if I remember correctly required only 1 character at Era level 45
