Two handed weapons

i have an idea...the two handed weapons upgrade theese weapons will deal more damage(2)but units with them wont be able to equip shields, alo slower attack rate(0.75% or 100% for swords)

this upgrade will unlock all two handed weapons(if you unlocked the original weapon)

also there is axception there wont be "two handed bow"because tht would be stupid......

and.....oh wait...rogues.....well....two handed daggers would be stupid too so...let he just have two of theese....and double his damage,maybe this is unbalanced ....let me know:)

((sorry for my bad english))
