Ramattra is currently the only hero added that does not match the ingame-view height to a mirrored Ramattra/his actual ingame height, Every hero tested in the Practice Range (accounting for the slight height boost from the character pad) is Eye/Head Level to eachother at a middle aiming point. Ramattra is the only one that is noticeable shorter in his in-game FPS view AND Nemesis form (only slightly raising his view it still does not reach even the Eye level of another Ramattra)
I think this contributes to the character feeling slightly awkward to play since in both his Omnic and Nemesis form he should be towering over characters, instead he sits at almost Tracer level and this makes lining up both his primary fires a little awkward since you expect to be aiming more downward at characters, plus this just goes against the rules of the game since practically every hero meets eye level to eachother.
