I don't mind it if it'll result in boss battles requiring more thought and planning, rather than simply being a potion chugging experience. In D2's terms I'd think of it similar to the moat trick with Meph, but I'd hope the boss has better AI then Meph did

This is not to say that every boss battle in D2 was simplya potion chugging experience, but alot of them were.
Bosses might require stunning, knocking back, slowing/chilling, out-maneuvering, distracting (summons, etc) or whatever to defeat, as well as careful use of your potions since they may have restrictions. There might even be some bosses that require team tactics like the uber trio in Tristram originally intended
