There is no win-win here and I get both sides of the coin.
Last season I managed 7 on my card and 3 on my brothers... and with only getting the 2 in the bulks (Sheff U and Villa) I still have managed 13 on mine and 12 on my brothers (has access to local sales) so far... I'd be absolutely gutted to miss Chelsea buts its a big possibility and even more so with my brother as he doesn't have the plus 4. Personally my view is the plus 4 should stand from last season but also similar to how they did the Everton FA Cup £9 tickets you also need to show you have been to at least a single game this season as that's not difficult to achieve.
That being said, memberships are sold with the loyalty tiers a well known fact. So if i did miss out, as gutting as it will be, atleast i know my efforst will be rewarded next season and so on.
