Pounce damage is being reduced by Reflexes, even though its description does not mention it being an attack. I've had champions Pounce on my Battle Rager that had Scrapper activated, and the damage was reduced.
This is working as intended - Reflexes and Evasive reduce damage from respective ranges as long as the damage type isn't Loss of Life - since the damage dealt via Pounce happens at RNG 1, Reflexes will reduce it.
