Can't you bait the Drakes into falling to death quite easily? I seem to recall doing that quite a bit.
They aren't the most satisfying enemy though that's true, they haven't got a particularly varied moveset and fighting them can take a while - and not in a fun "tense battle of equally matched opponents" way but more of a frustrating "strawberry floating stand still so I can I hit you" way.
Made it through Sen's Fortress and I'm now at Anor Londo. Hoping to deal with the (DREADED) archers via parrying the strawberry float out of them. Never really done that before, I usually longbow/poison arrow them from halfway across the map
