When using Tome of Shifting Words and casting Inferno Blast, the Flamestrike generated by said trinket will a) consume Hot Streak if the buff is active and b) cost the full mana amount. The latter is an issue as it costs a whopping 4800 mana, meaning you run out of mana in well under 3 minutes - causing you to have to twiddle your thumbs since the fire spec has no way of actively restoring it.

Prophecy of Fear's Mark of Doom debuff is triggered by the Conflagration talent's "Flare Up" effect (10% chance per Ignite tick). It is also triggered once for each cinder that hits if using the talent Cinderstorm, up to a maximum of all 6 cinders causing 6 Doom Nova explosions.
Right now I truly hope that a couple of changes are being made. First of all, since it basically means the trinket is completely unusable on fights that are over ~140 seconds, make the Tome of Shifting Words- generated Flamestrike be free of cost instead of the full 4800 mana. Secondly I would also like Hot Streak to make Pyroblast cost no mana, as fire still runs OOM even without using Tome of Shifting Words after the significant nerf to base mana regeneration. It's just a lot slower without using ToSW.
Keep in mind the mana issues are restricted to levels below 110. It's mainly for the pre-patch and Broken Shore scenario.
