I could make the same argument for KSM Mounts of each expac, Ahead of the Curve Mounts, Gladiator Mounts, etc.
This is meant to be an outdoor player reward for playing during SL. Unless you are also advocating for all limited time rewards, including AOTC, KSM, etc. to not go away, please stop trying to take away the same limited time feats from outdoor players.
Raiders and M+ers always say well, “It’s not meant for you, it’s not the part of the game you focus on” - well, shoe’s on the other foot now. The feat was aimed at outdoor players who have had 2 years to do this achievement. Not at people who don’t do the content.
Just like if I started a journey for KSM today, there’s a much smaller chance I’d complete it than compared to if I started when the season started. This is no different. The only difference is one is RNG based, which I think forcibly putting the Abom Factory quests on a rotation for the remaining weeks would go a long way to fix, but that’s about as far as I think it should be changed. (I even think replacing the quest achievement with “Craft every abomination” would be fine. But outright removing the Abom Factory requirement would be insulting. It’d be like removing an entire dungeon from KSM requirement.) You had 2 years to do those quests. Just like I’ve had months to do KSM if I cared about it.
I’d have zero problem if they kept the achievement available, as long as the reward, Veilstrider, was limited time.
I would much rather they stop adding limited time anything, and that includes all the mounts I mentioned, but while they still do it, I’m going to advocate for fair and equal treatment of outdoor players and their content.
