Mechniast could get some buff
+ start with Cyborgs
+ works as requirment for Synthetic Ascension
+ There could be anomalies to research poping every 10 year, giving us either robotic tech or some reward so we can expand our robots.
+You start with robot modding tech and can design your starting robot during creation.
+Provide unique 5% speed bonus to mechanist.
There is an always way to pop some bonus with delay so the origin will not be that front loaded.
The droid 2nd level tech from the start could be too much, but ability to custom from start is something.
It is important to notice, that you can get prosperous unification or any other origin (hegemony, necrophage) and using tradition and industry scientist get robots tech in 10y. Basicly if you want robots take something else than mechanists.
