Someone had to pay for the arena updates and player salaries going up.
Sad fact of the matter is that the Renovations were in lieu of razing the WFC and constructing a New Facility... the Original Mortgage was expired and paid off... In essence, it was replacing the Old Mortgage/Facility with a New Mortgage/Renovated Facility; basically a trade off of Facility Expenditures from one period to the next... without replacing... and actually cheaper. The transition was to be seamless and merely keeping the status quo... basically no savings but no great increase in Facility Expenditures, and actually less than replacement.
There should be no need to pay for the Arena Updates... merely continuation of Mortgage Payments started twenty years back... So the Renovations should not be an excuse to increase the Revenue through Ticket Increases.
Player Salary increases in a Cap based on League Revenue should also not be used as an excuse.
However, the years of no PlayOff Wins... brought up by another here... is another story, as is the Seasons without PostSeason Games entirely... The big problem I see is the lack of Revenue from the great Cash Cow~Post Season Games and its associated Revenue, such as Concessions and Merchandise~is killing the Organization and therefore, its STMs.
Unlike other Businesses where Quality and Success drives the Asking Price... Lack of success in Sports lowers the Revenue and, to keep up with the cost of improving the Product, Revenue must be increased somewhere... So we who attend must pick up the slack of a Team that generates little to no Postseason Revenue... And simply put; that stinks.
This is my personal take on the situation... FWIW.
BTW... My increase was $7 per Seat, per Game... Next Season's Payments starting this month, before the Current Season even ends.
