ARAM Rapid Demolition

So since the aram map changes I feel like the hexgates delay the first turret from being taken by some time since the team that got killed comes back to defend it way faster than before. I personally don't mind this but the Rapid Demolition challenge (taking the first turret before 5 min) becomes enormously harder to achieve. I think riot should change the requirement to 6 or ***maybe*** 7 mins to make up for the hexgates. I would assume riot has some data on this to see how much the hexgates impact the time the first turret is taken. What are your thoughts?
