) im not a dmg build fan
ive tried it for a while lured by the sim results and come to conclusion that the cheap build is not that cheap as it looks because it doesn't fit ur res prod ratio
prod ratio is 100/60 gold/lumber = 5000/3000 so the pro build is actually a perfect fit on ur res prod ratio if u have mines maxed or equal lvl,u spend 5000/2000 on troops and are left with 1000 wood to move ur troops around
so unless u can boost ur gold constantly or have mines unbalanced u will not be able to make twice as many troops as a pro builder by using the cheap build but merely 20% more(if u take into account the mass bonus)
and if u also take into account the cheap build vulnerability to spy attacks/nukes and the fact that using cheap build u will lose twice as many troops fighting lesser opponents than the pro builder the pro build is still the best choice
PS A combo of factors that make the cheap build a good choice:
ur alliance is attacked by another alliance and u lose almost all troops
u have tokens in reserve
u and ur team mates are active enough to be able to fend nukes
then u better go for the cheap build
so i think its safe to say that the cheap build is a good solution for desperate situations when u are loosing a war and u are wiling to spend some tokens to save ur skin
