The recent patch changed the way LRMs behave. Amongst other changes, they can arc down to much closer targets now, which is a much needed change of course.
However, it seems they now always arc down to the enemy directly, after they reached their apex. This kind of negates the artillery behavior of LRMs now, as originally envisioned by the devs. Now it's only useful to let them fly over a small hill in front of you. Previously the LRMs went up to their apex, flew in a path parallel to the ground and then arced down to the enemy from above, when they came within a certain range of the enemy.
Was this also an intentional change?
