Doesn't make a Logia DF ability any less great though. Especially when you have to factor in the use of Haki with Zoan or Paramecia DF's just to measure up to a Logia DF by itself. And you could say that any DF user relies on their abilities too much, not just Logias. But in One Piece, even that's a stupid statement since a DF changes a person's body so much that they kind of can't help but use their DF abilities. I could understand if there was some monumental drawback to using DF abilities too much, but there isn't. Actually, we could make a case for DF users not using their abilities enough. If we think about it, Aokiji could have won the war by himself with some extra planning to accommodate his DF ability.
