Do weapons need to be rebalanced?

I -Yoinking!- hate the boltshot with a furious passion. The little coward -Yoink- faces that use it while camping in a corner piss me of beyond belief. But it got me thinking, At the end of the day do the weapons in Halo 4 need to nerfed/buffed or are cheap players the fault for this community outcry for weapon rebalancing.
