Well I do not think that every class/race should be the same.
Since some people play the class/race as a kind of RP type role; and doing this would remove that aspect from the game.
The thing I wish they could all do is build all types of XXXX for the build skills they have.
Meaning that anyone which can build reactors could build them all; but then the race restrictions would still hold for who could use them.
This would apply to weapons, devices, shields, engines, etc.
Now maybe there could be a 'hidden' race % modifier; which affects the final quality output of the item you are building. If you are not the specific race for that item.
This way builders could build them all for the build skills; but if you want the 200% lvl 7-9 item, you are going to have to go to a race specific builder for it.
Other than that I still enjoy the game and love playing it.
Also many kudos, beer, cookies, ice cream .... to the devs for getting it up and running again.
