The fact that one can literally pelican-drop an Inferno on top of a galata is a sign that Pelicans are a bit too tanky. Unlike Bombers, which must be tanky enough to get in range AND kill its target, Pelicans only need be tanky enough to get in range and drop a unit before it dies. The unit it drops can handle the killing. I believe Nik has been experimenting with using Pelicans as meatshields to allow Icarus to kill Galata. I have heard anecdotes from many experienced players so far about why they believe that the Pelican's hp has been overbuffed.
