I just thought, since we upped the planetary attack and defensive systems, could it be a good idea to add a tech tree for weapons used only for planetary invasions? In other words, in regular PvP or PCvNPC, they would be effectively useless but against planetary defences, they would increase the invasion chance.

Yay? Nay?

I say yay. and you should turn this into a poll.

People have suggested something like this multiple times, along the lines of Troops. You can look for threads about that to see what people have said. I don't dislike the idea.
