The system can be beneficial or cost you more money. Each section has a required donation PER TICKET. If you are in a section that requires $200 per ticket and you have 4 tickets your booster donation would be $800 but if you are a tomahawk you can continue to give that amount and maintain benefits and away game/bowl game priority.
On the other hand if you are in a $500 section and have 8 tickets your contribution is currently $600 your are 'getting a steal' for great seats. Thus now you have a choice, increase your donation to $4,000 and keep all your seats, move to a less expensive section and buy 8 tickets at that contribution level. But to keep two tickets in a $500 section you must give at least $1,000. So it really depends on what you have had in the past, great seats at a low contribution or allow others willing to pay $500 contribution per ticket have your 'best seats'.
Some folks like me, will keep my seats in section 37 which only requires a $165 donation per ticket and still be a TH and keep my priority to road and bowl tickets. Remember, TH's are guaranteed 4 playoff tickets, so if you step down to Warrior you lose that benefit.
