I've not had a season ticket for some time. I've bought match by match for the last three seasons. In that time I've attended 0 of the televised games and missed one other home game (Brentford around Christmas 2014, I couldn't make it).
Not once have I struggled to get a ticket where I normally sit. I'm a member now so I get effectively two "free" games a season. I have the flexibility to not go if I have other plans, or work gets in the way, or we get moved for TV, or we're just plain shit and I don't want to watch us. The latter point which may well apply for the Preston game, I haven't decided yet. Either way it's my choice, I have no obligation to turn up.
Unless you have a group of you all sitting together there is absolutely zero attraction for a season ticket as far as I'm concerned, I cannot see why people would bother. This is why our approach to ticketing needs to change, it isn't 1995 any more. Although that's being generous, I'd say our current approach is more rooted in the 1960s.
