Ability to “save” rp for completed lined

Who would like the option to save regular research points after researching the end of a line? Israel for example, I finished the MK4M and dont have much desire to get the magach line so being able to “hold” rp earned for when new vehicles come out would be a great option instead of being forced to apply it to lower br vehicles.


This could be cool, but if gaijin implemented it it would probably cut the rp in half or even more. It could have a thing were when you have premium, it only halves the rp for example. But if you dont you would get like 25% or something.
