The only counter to that to me is that none of the packaging actually lists it as Series Two. Everything calls it Then, Now, Forever so if you were unaware this was actually series two it would be tougher to find. I wasn't aware until last year this was Series Two, and I'm sure others aren't/weren't neither. So for newcomers to the site I would think they would be easier to find as they are listed now.
While on this topic, I'm not sure why they need a second series anyways. Between Topps Now, Heritage, NXT, Women's and the series one, there shouldn't be too much to update throughout the year to make a second series. I understand Topps has to put out so many sets a year, but maybe if they cut down on the inserts from series one they could make another release based on some of them. Maybe Topps Tribute or something that showcases wrestling history and honors the Hall of Famers or something.
