the single rune playstyle has always caused one issue blizzard trys to avoid, and thats the removal of the need for haste when you have a 6 rune dump as your builder, as it takes you 11 second to use up 6 runes and 2 Frost Strikes at 0% haste then you factor in 2 rime procs and the subsequent 3 seconds of GCD it would take to use both Rimes and 1 rune instantly regened from 1 of 2 Frost strikes along with natural rune regen kicking in to restore 2 runes in that total time.
a single rune rotation quickly approaches GCD capped at minimal haste values which they simply dont like.
It was speculated in Early legion (before Night hold) that a all crit+mastery build that simply spammed Frostscythe and ran Shattering strikes would be viable (you would Frost strike after every third Frostscythe as it would always lead to 2 auto atatcks and 3 FSc to have 5 stacks of RI up). The legendary helm, ring, gathering storm and BoS promptly put an end to that. as Frostscythe did not spend runes fast enough to have good Gathering Storm uptime, less Gathering storm uptime meant much less legendary helm synergy and the theoretical build fell apart since NH tier was going to extend the need for more GCDs with 2pc (giving more rimes) and extend our resource generation with it 4pc (rime generating RP).
entire culmination of new legendaries + Tier bonuses AND CoF lead to the birth of Nighthold BoS and promptly stopped the FSc build from ever taking breath (intentional or Unintentionally).
