Getting rid of randomization altogether would probably lead to the kind of stock-stagnation that could endanger the line. I think partial randomization is ideal.Ideally I would hope they revise their plan further and stop with randomization of any kind.
Yes, I know that means prices would go up.
Ultimately though, I could see them cancelling the line altogether and maybe going to paper counters.
It would just mean more business for the metal miniature market, which could finally become cheaper again with some going back to using lead. Yay Reaper!
OP: Speaking in the long-term, no matter what happens to the current line of minis, there will be another line sometime in the future, so long as there are people playing D&D. That's how capitalism works: demand motivates the creation of a supply.
