Who says it's hated?
Only people I know who dislike 3d are incapable of doing it. A good 3d routine is harder to get right than any IMAC or F3A routine LEVEL FOR LEVEL (don't try to compare a basic "newbie" 3D Routine with an Advance IMAC one). Even IMAC comps have "Freestyle" routines in some places.

Gotta admit though
If your idea of 3d is just hovering around the flight area - it is pretty boring to most people but a routine of accurate and smooth execution of maneuvres such as Waterfalls, Parachutes, Falling Leaf, Wall, Cobra, Knife Edge spins, Rising flat spins (inverted and upright, Lomcevaks, Rolling Loops, Rolling Circles, Blenders etc (the list goes on) is a skill to be admired. Then to now worry to much about proximity to the ground makes it even better as a spectator sport.

And before I get slammed for seeming to put IMAC and F3A down - I try doing that sometimes too.
