Personally, I think it's bad for gameplay that homewolrd and other planets in homeworld solar system have random bonuses.
That unbalances things a lot. Not to mention what happens when DL get access to this in Apocalypse on their home planets.
Homeworlds should have preplaced bonuses.
So you know, if you are Iconian that, for example, that your homeworls has one 100% research tile and the other planet one 100% manuf. tile...
P.S.
Or if not that, at least restrics anything beyond +100% from homeworlds. Breaks game too much (no wonder there is no MP, it would be way to unbalanced for that

)
