Some questions about training grounds Q3

Day 1,736, 13:29 Published in Ireland Ireland by Duarte Goncalves

Hi everybody!
As everyone knows there are a new promotion regarding the training grounds upgrade. But, I ask, is it good to upgrade the 2nd camp to Q3?



I already have the free and the others 2 at Q3. And my strategy is to earn 5 gold from Super Soldier to spend the gold earned everyday on training.

Is it smart to invest on a camp Q3 spending 1,49 and gain 15 strength?

Right now, 5 gold give me 2 days training 52,5 strength.

My rustic math says that if I maintain the same strategy I will earn the same amount of strength in 2 days and the same amount of gold.

But what chance if I include 5 gold earned from Hard worker medal?

So I ask, if a good soul could present a nice, clear and simple study about the training grounds.

Cheers,
Duarte Gonçalves
