For all three of these, the cost to acquire it is quite heavy; if it's seen as "not too bad", then you're probably playing on tables with too many resources to begin with. The tech Opportunity Cost is also high as it doesn't count towards color-focused Objectives.If the player is investing in these, it's at the midgame, the part where Warsuns and large battlefleets can start showing up. If these resources are spent on these techs, they aren't being spent on ships that can go complete objectives.
I don't think its a problem of these techs being too good, I think it's a problem of too many racial techs being underwhelming.
