Just reset the mounts in a mop version for the next seasons
Malevolent > Tyrannical > Grievious > Prideful.
As Prideful Gladiator's Mount has already been giving away multiple times.
Brutal Season > Prideful Mount
And start adding tabards in to the seasons please, Furious Gladiator Tabard was never given during Furious Season, Neither saw 1 during Relentless.
