So .... it seems they really plan to swap the Gladiator mount for some reason but keep the armoredon the KSM reward. Now is the time to go to the forums and bring them to change it. Just recolour the s1 gladi mount AS IT SHOULD BE and use the new serpent mount for KSM or KSH.
Wasting gladiator models on 0,1% of players is bad enough already, giving each season an unique gladiator model just makes it so much worse, especially as the season 1 drake would have looked dope with green/purple/infinite effects down the line (basically a fel/shadowflame/infinite version ...).
At this point it just feels that some pvp dev has an hardon for giving pvp the best fomo rewards and being a special snowflake (because you know, now he can use both season 1 and 2 special transformations at the same time without having to go to the lastrum of transformation ...), meanwhile pve always gets the short end of the stick. We still have no elite sets there and the Lava Kodo is just a bad joke compared to both the Viscious mounts (which are also unique each season) and the Gladiator mounts. Atleast in Shadowlands, the Deathswirlies looked on par with the Gladi wyrms ...
