I think it's more that the park have decided the best way to improve the ride is throw more money at it over a long period (I.e. staff wages) on a ride that already needs the highest number of staff to run it minimal...
In a time where budget cuts are getting bigger and bigger, it doesn't make much sense to add more staff who will be paid higher wages 100% of the time... Maybe they could/should have just done with more effects in this exit corridor thing, but I dunno if the re-rideability will ever increase for it now...
I'll find out Saturday, with people who have never been on the ride in any guise anyways, so it's gonna be like we're all riding it for the first time...
