Frost vs Unholy
Frost in mythic+ with Frostscythe and Sindragosa's Fury is the easiest DPS spec in game for a melee class to play with.
Frost current RA/Obliteration, short cooldowns without GCD... spending 2 ressources without any fixed order...let me think for a second...
Frost fits better to all the other legion class/specs while Unholy got wound=old-combo-point mechanics even rogues/ferals got rid of, slow ramp-up for an allready slow DoT-centric spec with cooldowns need to be managed while running to even net a DPS gain. If we discuss how easy or hard Unholy is, we should not compare it to Frost but to all other specs in game, because Unholy is clearly an outlier spec with game mechanics from the past.
