Yeah, it isn't a problem for me as I just feed it scrap boxes from my quarries. I get around three stacks a day (I'm making hybrid panels exclusively with it) so that isn't too bad at all.
In my next world, I will likely set it to require 1,000,000,000eu per scrap (so 166,666,666eu amplified). As well as set some other hard mode stuff which the MindCrack pack doesn't have set.
haha, if you want to make your game harder, just don't use any lava, solar, watermill, windmill, (bio)fuel->combustion engine-> magma crucible(the converter). 16m/uum is perfectly fine, since the source of energy is the real problem.. and I really recommend enabling all TE hard recipe (especially the steel requirement for machine frame).
Anyway, Iridium is now pretty easy to get, 1 ferrous ore = 1 platinum dust, 36 ferrous ore+other materials = 1 iridium plate.
