Our red fire is even different from fire mage's fire, which is yellowish orange while ours is a deep, darker red.
What color is fucking Sargeras? Oh, right, fucking red/orange, not a green fire avatar. Even his sword is a dark fiery red. The coven of Shivarra's fire tornadoes are red. Aggramar reborn under Sargeras was red fire. Argus under Sargera's control in mythic phase is fucking red, not fel green.
Red suits warlock just fine. Green is awesome, but there's no reason to deprive warlocks who like red fire from it. It goes great with many warlock sets, including the iconic Corruptor's raiment, old school malefic tier set, among other black/red motif tier sets.
