Making this post for some visibility towards what I am witnessing as an issue within balance. There are currently a number of issues that are making Fire soar above frost in damage within the current Tier:
Fire 4 Piece is significantly stronger than the Frost 4 Piece
The Fire 4 Piece passes Frost in its strong suit: Single Target.
Fire scales better with crit and mastery whereas Frost just scales kinda well with Multistrike.
BRF is itemized heavily towards mastery and crit with little Multistrike in the instance.
I would consider these issues, and there are some that are non-issues but more situational. Nonetheless, they deserve some visibility:
BRF fights are heavily skewed to favor fire because of AoE
Now I recognize it's a bit late for any chances to set bonuses, but scaling could be changed to ensure that Frost isn't entirely surpassed by the next tier and end of the current one. (It already is on many encounters).
In fact, Frost holds none of the top 200 rankings for any encounters on BRF (in any difficulty). AoE encounters are going to fire, and Single Target to arcane. I recognize (and support) specs having strengths. I want fire to be better on AoE encounters, and Arcane on single target. It gives variety to the specializations; however, frost doesn't currently have a spot in progression raiding. Where should frost's strength be? Cleave and mobility? Is that too niche?
On fights like Iron Maidens, Oregorger, and Hans and Franz, frost should be number 1. Cleave and mobility. I hold a number of top 100 rankings in frost for heroic encounters, and the numbers still pale in comparison to those of the other two specs.
For the record, I am not saying that Frost is not viable. That would simply be a lie. But as a progression raider, it would be nice to validate the choice every once in a while.
We face the age old problem of frost's lack of scaling and "jack of all trades master of none" style that isn't conducive to progression raiding. What do you think can be done to give frost a solid "strength" in raid encounters?
