If you want you can now camp in one era,You will get a lot of diamonds.It's a very useful GB.I might also consider to go for it.
I'm one of those - just have prioritized other GBs before now: CDM, Arc, Alcatraz, and Atomium. I'm in Modern era and need PE goods for GE4 so it's a combination of needing the space for the considerable size it takes, and lack of goods.I'm only in CA but started farming blue prints as I see it as a way for extra diamonds. I'm surprised how few people in the multiple millions of points I see on V without it.
Atomium
It's more guild goods. I'm a guild-first player. Currently producing 30 goods a day for guild and climbing.Seems odd when you have Arc for Guild goods and Traz for Happiness. What am I missing?
CF makes goods (from quests). It is great for that, I think the best for current age goods.
You can actually do/be bothI suppose it comes down to a matter of an individual's style of play.
If you're Aggro, then a CF would probably not be in the first wave of must-build GBs, since you're going to be concentrating on those that give ATT bonuses and that which gives free units.
If you're a Farmer (my inclination), it should be among your must-builds pretty early on, as one of the 'crops' I plant is the Recurring Quests (usually in the form of "Gather XXXX Coins" and "Gather XXXX Supplies") and the CF increases the harvest of whatever you reap. If I hang out in an Age for any extra length of time, it's probably because I'm in a "sweet spot" where I can do those recurring quests multiple times each day and the reward is boosted by the CF.
wow nice! laclongquan... if i may ask, how long have you been playing?
