Here's what I'm seeing...
*blah blah blah* *balance balance balance* *WORDS*
The short answer:
Minecraft is YOURcraft (e.g. "mine"? as in the possessive?) It's up to you to determine what, in your world, is fair or unfair.
Don't listen to peer pressure; if something suits your playing style, do it.
My personal opinion, FWIW after my "short answer":

Something that gives high rewards for a low amount of input, such as a mod I saw earlier on MCForums that gives 5 (yes, 5!) nether stars for some cheap-o combination of diamonds and gold, is drastically unbalanced. Now, the work that's put into killing a Wither is totally more significant than the work that goes into gathering some diamonds and gold. And five Withers? You've gotta be kidding me...
OP? Totally.
