The more the regular races are changed, the more difficulty I find it to play a custom race.
During Beta 1 and 1a there was a little gap between a normal and a custom race, but this was balanced out through adding more points to the custom race for Abilities.

But now under 2a I find that the amount of techs available to normal races have increased, and decreased for custom races. I'm fairly certain price went up when buying techs for a custom race.
This leaves a custom race significantly behind when the regular races sports various techs such as Xeno Industrial Theory, Armor theory, Xeno Economics, Starship Defenses. And usually sporting between 4-7 of those techs among others from the get go.

I'd like to see more points available for Custom Races to purchase starting techs, because as it is right now it's not possible to reach any of the Tech combinations of the regular races with 6-7 techs.
