Need help with geonosian datacron

I need help with geonosian datacron level 1-3
Our guild put a wall of geonosians as defense in TW
I have relic 7 Brood alpha and the rest relic 4
What is the ideal stats from level 1-3 to put on geonosian.
I was thinking level 1: protection
Level 2: health
Level 3: also health and protection
My Brood alpha goes first maybe put level 1: tenacity
Level 2: tenacity
Level 3: any mechanic that give health and protection?
I have to do a lot of level 1-2 rerolls that's why I'm asking
Thank you in advance!
