in general i think, upgrades arent worth the money.

the strenght of a unit is only raised by about 1/20 of its basic strenght while its price increases about 1/10 of its basic price.

i never use upgrades. if i have 50 or 100 bucks left i buy armour for xbows and archers tho.

this aint rtw, rite but it aint mtw1 neither wich wasnt perfect but still much better balanced.

the clan war belt in mtw/vi used the 2-max-of-a-kind-rule. mite sound like a limmitation but in fact it intruduced a tactical variety wich i liked better than the regular 4 max.
there are some good 2 max armies in mtw2 too, alltho they mite be weaker than some 12-heavy-cav-armies. thats the weakness of the game itself, not that of a certain army.
