Proddy, i am not sure if i would go so far as your idea of ageing troops.
Because people play at different rates, the difference that this would make across the whole player base would be vast, from the person who puts a great deal time into the game too just the casual weekend player. ie some people would get lots of usage out of the weapons/troops and some people would get very little usage.
Maybe look more at a usage amount, therefore people playing at different rates would be uneffected.
I personnally would just like to see finished weapons taken out of the adventure loot rewards and only have production materials and resources.
atm. very few people have built the high end buildings because there is just no need to do so and the one's that have, have just done it for the fun of it.
btw, i don't understand how you think that it is not easier for new players, when i first needed, for instance Steel Swords they were at 1:1 for gc, (actually that is why i built a steel weaponsmith) now you can get a 400 stack for 140 gc.
