Presently, when you follow a redeem link, you automatically open the pack in no matter whether you clicked “Open pack” button or not. But I think the opening of any link shouldn’t cause any action.
Also, redeem page lacks info about series, there is not even the link to the series page. For example, to decide to collect a series or not I have to find it on the site and then check the series’ info.
And only when I like it, I can safely open the redeem link.
