I was thinking of how gains are based on networth and to reduce nwpa to decrease you networth.

It's a half joke/half just try it for kicks type of build.

What did I come up with?
Run barren lands!!!

I did a simulated build for Dwarf Merc (Only worked for age 37 but I hope the figures are right.

Goal? Just whore gold and resources but instead of being a BIG BANK, lure in stupid people to try and bottomfed you, causing low gains, high attack times and be able to just take hits. Basically a tank.

Build?

Dwarf Merc/Artisan

33% Barren Land
20% Banks
10% Farms
7% Towers
10% Guilds
10% Forts
10% Watchtowers

Strat? Run all defence @ 50% draft. @ 120% BE you'll get 10k specs
which is around 60k def or 0.5454... DPN. Very high.

110k NW for 1k . Not bad since everyone should be about 140-200 mid age :P.

Try not to put sci but sci is like 5% income, 5% BE and maybe 1% pop.

Supply your friends with runes, solds, food and gold :P. Send 2k solds to lose 3k nw! :P

Problems? To be viable you have to be significantly smaller than your average prov in all your kd. Your not gonna supply much if your TOO small, but if you get too big you can't defend yourself because your teammates can't do the same.
This is more of a joke for those who are bored and lure noobs into attacking with high attack time and into fog for low gains.
