it's going to generate a LOT of resources. You'll want to make sure if you put it in, you're getting a reasonable amount of resources. I ended up with ludicrous amounts of copper since I have three different mods generating it.
that is typically resolved by disabling ore gen for overlapping ores so there is only 1 type in world gen.
now @general topic
as for the general concept of "mekinism is op". it has not gotten stronger really ,but other mods have gotten stronger .
Te has Native 3x and 4x that are reasonably sustainable (3x more so then 4x), the digiminer is/has already lost some ground as in there is a block in another very commonly used mod that will do the digiminers claim to fame "mine only this ".
To the people who say x5 is op : have u ever seen how complex going from 4x to 5x , besides that look at the price to maintain(or even start) 4x ore process
WITHOUT Pam's harvest-crafts salt being mass crafted(lets face it this is a cross-mod exploit) u burn through a large amount of copper and a decent amount of tin to start and that ignores how slow the smaller towers that produce the brine u need are .There is also the old standby of why not just quarry more instead?
As for "insane power production" at its end , what good is all that power at endgame if there is nothing equally power demanding outside to use such power(batterys/power spheres don't use power) and its just a bigger version of the generators u already have that are already working fine for u.
