Before, to get Novalith by TEC, it required only one point in extended range missiles and extended range missiles just required only one point of the research before that.
But now, the Novalith requires 6 points in Extended range missiles and it requires 4 full points in the earlier research.
But the Vasari Kostura only needed 8 labs to get it before and after. So, by upgrading the research paths the TEC will get Novalith very very long time than Vasari.
Vasari still need 8 labs before and after. The double research time increased the build time for TEC but Vasari remains unaffected.
