I get that you don't like the place and won't spend time there, but as someone who goes regularly and spends 6-8 hours at a time at the Campus because there's always something new and different happening that I don't want to miss, agree to disagree.
This move was clearly a response to the success of the constant character additions and updates at Avengers Campus.
And as noted in my other comments - things AC has that GE hasn't and needs desperately:
unlocked timeline
all the characters with constant updates and additions
multiple shows with constant updates and additions
merchandise for all characters in every iteration (doesn't matter if comics, MCU, D+, AC, etc. - it's all there)
epic theme music soundtrack
attraction that everyone can ride
(again, people here like to look down at Web Slingers but it's a fun attraction that all ages and those who suffer from motion sickness can ride and participate in - I'll never be able to go on either GE attraction but have enjoyed Web Slingers multiple times)
So while you can continue to disdain AC, it still has plenty of things that GE doesn't have and should.
