I think people are overreacting to shippy getting a strong cleansing beam. He really hasn't changed all that much. I think he was underrated before, yes, but he is still heavily reliant on his troops to actually do damage and he doesn't really have many direct buffs to them if we ignore his exceptional ability to move troops around the battlefield.
Displacement followed by glassing is a combo only counterable by an immediate teleport or invulnerability. Due to displacement clumping up the army and you losing control over it there is no way you will split against it.
Ship should always get there because Ghosts are the best scout, cloak grunts and the Honor Guard are amazing, and Spirit Assault's units are unkillable in the midgame.
Also, people are not very good yet at dealing with Glassing outside of like 10 select individuals.
