I had not tried Magic Seeds before, as it was going to be coming out of the pack, but gave it a whirl last night. And I think I now better understand what you are aiming for. I love how the seeds tie you into the store and provide a reason to chase coins. This looks to me to be a real strength in the pack. Caigan had written there were problems and a switch to a new mod (Fluxed Crystals or something like that) was in the works. I hope that it captures the goodness of the store providing options that I see now.
The glowstone seeds are available in there and since I had chosen not to go to the nether, I had to work to get glowstone from somewhere. Nether quartz was also available in the store, but now I had to choose what to do with my vouchers. Lovely dynamic, especially since I am also trying to build an ender pearl farm, putting more interesting decisions in my path what to do with limited resources.
The RFTools autocrafters are really useful in the production process. I was going to checkout their storage system, as I had seen it in a Direwolf20 video, but it seems that it is not in the mod anymore. I was thinking of not going down the AE2 path this time, but need something to do the sorting. I have done the chests with pipes before and am interested in a new option. Does anyone have any suggestions?
