If it doesn't matter, then why do greedy OS advisers keep changing it?
Prior to the "let's get rid of our 1982-84 overstock" scam, whereby OS artificially extended the BA to 1984, there were NO real arguments about the End of the BA (Death of Phoenix/Days of Future Past and the Start of the CA (1981/82 - a massive number of reasons), and it was money-hungry dealers that caused the current problems.
They should have left well enough alone, rather than only thinking about $$$$.
Ok, I'm not disagreeing here. Why would changing the Bronze timeline affect sales? I usually collect storylines, artists, or 1st appearances, not a certain Age.
