Better question is how does one relocate to a larger facility and nothing changes on the archive front. If lack of space = archive, then should not more space = less archive 0.o
I would not universally offload the archives in the new facility, as that needs space for new miniatures to grow and develop. we don't want another situation of molds on top of the toilet tank after all.
but as has been stated, the Tundra Wolf in this specific instance has gotten on the top 2 every time it has gotten up for special retunr (three times counting this one if I recall correctly)
now how well it sold when in that return, I can't say, but it does seem to be popular enough that fans want an oppourtunity to buy AND it is a mech that exists in the currently supported era of the game. that is why I favor it being pulled out beyond the special return period.
of course Ironwind has to answer the question "Does this make business sense for us?" and they have data we don't.
