I would say that 50 forge points is worth 10k goods wouldn't you?
Yes I would agree but I've seen the math too and you assume way too much.
FIRST, that you can trade 2/1. I noticed as you got to lower ages the ratio changed.
SECOND, that you can even get the trades down to your level. Unless you have diversity in players, there will always be dead ages.
THIRD, GBG. You're not producing anything else but goods...most of them are going to wind up here. That could be a good thing. If you don't mind that none of your GBs are getting leveled because of all the time you'll spend doing this.
FOURTH The amount of work. It aint just listing trades. The most important part of this is finding a top guild and diversifying your friends.
I have no problem with the strategy. What I'm saying is that you need to realize all the effects and plan for what you give up. You will give up leveling your GBs or spend 24/7 on this game.
I've had 3 people employ this strategy. One with great success. He became the #1 GB fighter in our guild but he quit the game and the other two changed their strategy.
