Limited time items

[Myth]

I think the biggest question is. Why were these items removed in live?

Box of abu kar is obvious. It was replaced by a plat sink [tink bag] to remove exploited/farmed plat from the economy. Is that needed here?

Lustrous russet and cryosilk? Obvious. Too many classes can use it and it becomes a gearing bottleneck

rubicite? Why removed ?

Manastone? Obvious. Much like why mod rods were changed. Raids would have to be balanced around them. Yet verant had to leave the old ones in as to not piss off players. So future functionality of them impacted but "classic" use was
allowed

Jboots? Needed to be switched to a quest. Too many players want them and there was only 1 place to get them. With quest they added AC to 3(?) zones. Ek, Sro, oot plus it was another plat sink

mask? (pls correct me if I'm wrong). They didn't want everyone being able to be good and evil. It wasn't until velious until religion affected illusions. But the change had already been made to bard/rogue only.

so I can see taking out lustrous russet and cryosilk, but the others. Why?
