Agent Gibb, my reason to refrain people from talking about all the possible sets that Landorus-I possesses is because we end up having people saying shit like, "Landorus-I can do both physical and special set well, it can set up rocks, cm, set up a sub, it can sludge wave KO Celebi and Psychic KO Gengar, it can Gravity KO Rotom-W, it can be scarfed and kill your Starmie - halp it is unpredictable / has no counters!" People end up listing all the possibilities and assume that Landorus-I has 6+ moveslots to perform two or more of these roles. We can literally use this flawed method to ban every good Pokemon in OU, and it's sadly a flawed approach that I've seen bad and good players alike used in the past -_-
The fact of the matter is, it's a give-and-take. Let's take your example; if Landorus-I is using Sludge Wave, it would be over one of its coverage moves or Rock Polish. If Sludge Wave replaces Rock Polish, then that reduces Landorus-I's sweeping potential drastically, while I should not need to tell you that replacing HP Ice or Focus Blast for Sludge Wave would leave you with more checks and counters than the original set.
Yes, Landorus-I may use Sludge Wave to defeat Celebi or Gyarados, but it's an overall inferior non-broken set than the original - now I can expect Ferrothorn, Kyurem-Black, or hell even Skarmory to check it because it lacks Focus Blast now.
Yes, Landorus-I may use Sand Force instead of Sheer Force, but that means I do not need to worry about being swept by Rock Polish Landorus and free LO boosts.
Yes, Landorus-I may opt for U-turn instead of Rock Polish, but then I don't need to worry about being set-up bait for Rock Polish, and have more options to kill Lando-I.
Genesect is different, because its Scarf and Rock Polish sets both hugely influenced the metagame. Scarf Genesect was the best Scarfer around, rendering DD users, dragons, and fast psychic-types a liability. It fits the support characteristics of ubers to the tee. U-turn Sheer Force Lando-I or Scarf Lando-I do not possess the same impact as Scarf Genesect had in this metagame.
I'm all for discussing the various broken sets that Landorus-I may utilize. However, at the moment, Rock Polish Landorus-I is the only broken set available from my perspective. I am sorry that I jumped the gun and thought everybody agreed with this conclusion. So let's take a step back and focus on this topic: Identify and Explain the Landorus-I sets that you believe are suspect / ban-worthy. Once we identify the suspect-worthy set(s), the discussion will focus solely on the broken set(s).
