I agree to the point where I wont level an alt without road to x active.

Am I capable of doing it? Yes. Is it still a slog at times even with double the xp (which makes things go by more than twice as fast because it lets you skip some of the annoying spots where you have to grind stuff out)? Absolutely.

Doing 1 to 5.2 finished and all craft/gather maxed in 5 or 6 days is a huge difference from doing it in 13-16.
