an idea to reduce turtling

[Wrana]

I'd say it has more than a few issues. At least one was already mentioned - there are nations which have a strong research and weaker troops. Plus, different paths require a different research level to really affect game. I think you are offering solution to an absent problem - if you don't want to turtle up - play a bless rush nation. Of course, you may be mowed down when your opponents complete a neccessary research - but that's the game. It doesn't consist of tank rushes... :P
