Comment 10 for bug 895047

it seems only logical to have the legionnaire pathfind a way to the target; that way if there is something that prevents him from getting close enough (like a carrier in the water) he wont just teleport onto the water/impassable object and die. I honestly don't see how the legionnaire would work if he didn't use some form of pseudo-pathfinding.

It's still not really a big bug, considering all units, teleporting or no, have a similar behavior when targeting offshore targets. The main difference however is that after so many failed attempts standard units will give up, while AFAIK the chrono trooper will go at it for ages.
