I think that altitude should not matter although perhaps range to target should. What I mean by that is missile x takes y amount of time to travel a given amount of distance. If an aircraft is high up enough it would be easier to avoid the missile but it would still be coming after them.

On the flip side of this things with the lancer style of aim and fire where dodging is much much harder due to the speed of the projectile need to be balanced. This would possibly include decreasing damage over distance. Nothing is scarier than trying to fly a reaver through a hail of lancer shots because it is so hard to dodge them.
