Answer Wiki. If a rocket went straight up, it would either continue in that direction and leave Earth, or it would fall back down, depending on its velocity. Most rockets intend to enter orbit, which is an elliptical trajectory, and it's much more efficient to arc into this trajectory than to go straight up and then accelerate laterally.
Pharah's rockets fly straight to its target (no arks), do splash damage and also do small knockbacks as well. Rockets are great for short or long range, and deal a decent amount of damage. Rockets have no fall-off damage, this means rockets will do the same amount of damage regardless of how far they are. Rockets do more damage on straight contact than splash damage, but you may find while playing Pharah that it can be easier to hit enemies firing rockets on the ground next to them especially when you are not flying in the air at the time.
