Death Knight Internal War Season 2 PvP Elite Look Eye Glow, Smoke Visual Effects are weak

The Death Knight Internal War Season 2 Mythic set has red smoke effects and eye glow effects that are dark and bright, so they look clear.

However,

why is the Death Knight Internal War Season 2 PvP Elite Look purple effect (eye glow, shoulder smoke effect) designed so that it’s not visible?

I request improvement in this area.
