Despite your preferences, there is, however, more than one correct placement of "however."

Hi! It is unnecessary for me to revert your change at WP:ADM, but for your future reference, this is not true: Proper English usage dictates "however" should be at beginning of sentence. Please see the Chicago Manual of Style. (This is a Q&A, not the actual manual.) Also see the Purdue OWL here and here. (You'll have to search for "however.")
