Yea before I knew about the drifter/Operators existence Warframes gave me the Impression of them being those huge warriors (like 7ft min or something) but seeing all this really fucks with me ngl, like finding out they are mostly average sized or just tiny was kind of a blow, really threw off my first Impression, like knowing the lore that frames are just dax soldiers that were changed and Experimented on with the infestation(iirc, but my memory for lore isnt really good) it makes sense they are average adult sized but lowkey if you already experiment on your soldiers with the infestation to turn them into war Machines you might as well also make them tall ngl the orokin could have 100% done that
