I really don't like Switchbacks because everytime we've had one, it has failed catastrophically (best done was TAR27 and even that was stretching it).
I do like though, some fun nice little touches to earlier seasons locations (the TAR3 Switzerland Fountain on 28 <3 Mika on the water slide lol <3), but nothing overboard like repeating tasks.
You know what they say, repetition of things you already know is pointless and lazy.
That said, we need another #WatermelonGate-esque task to go viral. Really.
