The lack of sweeping is the problem. Being bulky doesn't have as much value in-game because its more about KOing a range of opponents efficiently. 65 attack isn't going to cut it.
It's not so much that its hard to train, because I'm sure with those defences it will win the war of attrition. However, it does so very slowly. Why take 5 turns to KO one guy when you can use something else that'll also KO it in just 2 turns?
