I agree, in fact, I actually have a Landorus-I set I use when I'm bored:
@
Trait: Sand Force
Nature: Jolly
EVs: 252 Atk / 4 HP / 252 Spe
- Stealth Rock
- Imprison
- Earthquake / Stone Edge
- Explosion
It makes a nice suicide lead. Imprison cancel's moves known by the user, which means you can always seal the move Stealth Rock. This works great alongside Pokemon like Dragonite. Most people would think this set is outclassed by Azelf; however, they would be wrong. This set can actually prevent TTar from getting up rocks and it can set up rocks itself, as well as never losing to sand residual damage.
However, the introduction of BW2 has hampered this set a bit when SashSR Terrakion lead, but it still nabs those Explosion kills and it usually does work. Stone Edge is slashed with EQ just in case you hate those Gengar switch-ins.
