Why have plasma when you can have DU and extended range cannon in physics. I say if you were going to move it move it to a tree where there or no cannon or machine gun upgrades available like Mechanical engineering perhaps, then it would get a lot more use.
weapons in mechanical engineering would need to have rediculously long research times or you would have tanks way faster then in any other tree = theres a good reason why there are no weapons there
You could also break up the tree, and make vehicle upgrading its own tree, so as not to confuse new players.... And also create a new cannon or MG for electrical.
It is almost it's own tree. The only things in there otherwise are armour and engines - pretty damn necessary for vehicles anyway. It's been thought of before, but...I think there's a long-term persistent idea to rework the research tree. So whatever comes up then, and when that comes up...well.
Exactly. Although I am not against the idea of merging plasma with nuclear fission research and being renamed fission. How about you flasche?
