Personally I think £35 still represents a very good deal for one year's travel. You only need to make one very long journey or about 3 journeys of say 70+ miles and return to make that pay. I suspect most of us (especially those of us elderly senior railcard holders) will easily manage that. If not, then a reasonable number of local journeys (one or two each month) will.
Undoubtedly it remains good value and indeed one would expect it to rise in line with rail fare inflation. Where these things need a degree of care is that other changes don't quietly get sneaked in at the same time. Ticket types where they don't apply, new tighter time restrictions, minimum fare conditions, reduced discount levels, only apply to online ticket purchases, must not be a
UK▸ resident, must live near to a station that is within the area of validity, must buy a reservation, not valid when travelling with a bicycle, delay/repay not available, no "get you there" guarantee, etc.
