i dont thinnk you realize just how big the gap is, best arcane log vs best frost log and there is a 15ish% gap in favor of the frost spec that is pretty god damn far imo, but with that said arcane is good enough to be played on pretty much everything, and it is a very diverse spec compared to frost but its a waste in nighthold bcoz most of that diversity/versatility just goes to waste on quite a few encounters, where as frost is essentially perfect for most if not all encounters in nighthold atleast those that matters.
