bare skin and fishnets aren't the best camouflage. and it doesn't really protect against the environment. both of which are important for a sniper.
to put this in perspective here were two other snipers in mgs who were given the highlight
the end. who obviously isn't loveualized at all.
and sniper wolf. you could argue that she was loveualized (i mean the concept artist did like 12 nude sketches of her which he described as "lovey") but it definitely wasn't the entire point of, well, her, and even if she is it's not to the extent of the character shown in the op.
so. well. yeah.
