It doesn't, it was a joke.
However, its still concerning that Frost has a HUGE amount of parses...yet still underperforms. E.g. on Mythic 75th percentile, Frost is on average second lowest on the rankings, only beating BM (which is also popular
), yet it ranks 3rd highest in # of parses, beaten by Havoc and Aff. Havoc is also doing poor overall, but Aff is definitely the Flavour-of-the-Month having over 50% more parses than Havoc/Frost AND ranking #1 overall highest. Granted Aff isn't perfect in every fight, but when it excels, it
destroys everyone else.
Having a high # of parses yet low ranking indicates that the spec is underperforming because popular specs also tend to have the more skilled players, regardless of the spec's performance. Gamers are sheep, and we flock to the specs we perceive as being powerful. If all streamers and high-end players started using Arcane, the playrate of that spec would skyrocket and so would its overall performance. We already saw this with Frost at the beginning of the expansion, when it got buff after buff after buff even though it was already VERY strong...but nobody played it and its stats looked awful because the high
-end players were ignoring it. Then in NH, people started playing it, and realized how OP is was. Inb4 Legendaries and AP preventing people from switching.
Back OT though, I can't really think of anything Mage-specific for boss tips aside from using your immunities liberally. Since Frost gets 2 nearly back-to-back, you can make the healers' lives easier by soaking some of the player targeted mechanics like Marked Prey on Varimathras.
