I think they have a right to (I'm a Gold Member, btw). They pay more money and attend more games. It's not fair that a ST holder for 30 years who has just under 8,500 points is in same phase as part time Joe who bought a gold membership at the start of the season so he could buy a ticket for the match against Man City and Liverpool.
I agree that all ST holders will get a ticket, but there will be a squabble over the best seats in the house - which on merit should be offered up to the more dedicated fans first. That's the whole point of having a loyalty system in the first place.
It could have been organised in a fairer way by adding more phases. This type of scenario always causes anxiety as some are desperate for a ticket. A bit of common sense from the club would have helped.
