Wasn't sure how too word this right, sorry if it comes off a little odd.

If your planning on using power items in this mod, like rings, picks, etc. have you had much thought on the type of "energy" you would use too power them? An idea had popped into my head last night while testing out a few mods in Minecraft. In EE2, the passive EMC generation method of collectors and relays was smooth, but ended up being too easy too exploit as a diamond generator for example. I can agree with your plans on redoing or not using them in EE3.

A way this could still be done while minimizing the creation of free diamond trees would be too power the EE3 power items using a form of arcane potential(a separate energy from EMC) that can be generated using EMC, or passively from transmutation generators. The conversion from EMC to this arcane potential could be a one way transfer. This way a passive way too charge the items can be used without that energy being exploited too generate free matter.

Hope you are able to use what I have typed in some way, or it at least helps you come up with ideas of your own.

Why not remove EMC altogether and just have Arcane Potential as a single source of power. Nice idea BTW.

The idea of having a different type of energy for power items is simply to keep Transmutation pure. This way matter can only be created from other matter(EMC). But, it would allow other things to be charged up both passively or by converting EMC. Like powered pickaxes or a ring of protection.

Transmutations would remain just as useful for converting unneeded blocks into something you can use. And it would most likely make some of the balance calculations a bit easier to manage.
