Well Glarg,
You tell a half truth. The ARC generates more guild goods than the same level OBS. In fact, I believe it is a lot more. But that can be verified on the Great Buildings Thread here, which is a great one to look at. YES, an ARC is a very powerful GB and some do not know the true power of it.
Shark Hunter, the truth is this. Right now, NO ONE should rush or race to the new age. The new age is for suckers and I made a long post about it on the Feedback thread for the Arctic Future Age Feedback Thread. I believe I was lucky # 13 there, worth the read. Sadly, you or your guild mates cannot turn back time and go backwards to FE Age. But that would be funny and I would love to see people requesting to go back and age, LOL. That said, I am sure in due time there will be a use for them and please remember this game is NOT a sprint, it is a marathon. If you made it to FE Age, you can hang in there long enjoy for the next addition after the AFE newest addition. Personally, I stayed in FE and I thought ahead, but that is just me. Tell your guild mates, to hang in there, in time I am sure there will be a use for them. Right now, there isn't but that does not mean to do something twice if you start removing GB's and then regret it later. Hang in there. Some made a mistake and now they are stuck, sorry but it happens and it is just time you guild mates will have to wait on. In the meantime, the goods will grow, so be thankful for that.
I almost forgot, build up your ARC, it is more powerful than you realize or know. Trust me. Tell them it is very worth it. Despite what others say, the OBS is a waste compared to your ARC anyway. There is NO NEED to go past a Level 5 on an OBS, if you have an ARC.
