5th Gen LU
5th Gen LU or 5th Generation LittleUsed (also known as LesserUsed) is the tier below 5th Gen UU and above NU. There is no No Preview version of the tier. The former Dream World version was removed as the already small player base was being split by the two tiers, and there was confusion about which Pokémon was in which tier for new players. Wifi is the default tier so Wifi Clause is enforced.

Cresselia was quickly banned from LU, as almost nothing in the tier could break through it. Gorebyss and Huntail were then banned, primarily for their ability to use both Shell Smash and Baton Pass. Rhyperior was deemed too powerful for the tier, as was (somewhat controversially) Medicham. Slowking has had a suspect vote on it but it was not banned. Medicham was test un-banned because the ban was pretty controversial and 2 counters fell to LU. Sharpedo and Abomasnow were banned in LU as well. Sharpedo was too powerful and nearly impossible to revenge kill, and Abomasnow supported Hail far too well for LU. In November, Omastar was banned from LU because its sweeping capabilities were simply too much for the tier.Tornadus was about to be retested at the end of 2011, but then it moved to OU, so its going to be suspected if it drops again. Excavalier was suspected but The community thought its easy enough to check it, so it stayed. Rain was suspected too, but at the end of the Discussion everything stayed as it was before. Durant was banned at the beginning of January, because it was just too strong and had close to no counters and could play around the counters with Baton Pass. Virizon has been suspected before and then moved to UU. When it dropped to LU again it got immediatly suspected and was banned for its variety and power and because of the fact that you need at least 2 Pokémon to check it. Honchkrow was suspected but rose to UU by usage before a decision could be made. Moltres was also suspected and banned for being able to run a powerful offensive set or an effective Toxic-Stall set allowing it to beat its normal counters. Omastar and Moltres were recently retested in LU because a large portion of the player base felt they weren't broken in the tier anymore. Both are dangerous Pokémon that shouldn't be taken lightly, but Moltres and Omastar were unbanned. Later, Medicham was retested for much of the same reason as Moltres and Omastar.
 Current Metagame
The current Metagame is pretty offensive, based around strong sweepers like Moltres, Gallade, Sceptile and many more. Even premier defensive Pokémon are seen running more offensive sets. Most teams carry Stealth Rocks to help deal with Moltres and other powerful Pokémon weak to them. While Regenerator cores are still seen sometimes, they are not as domintating as they used to be. Regen-cores are based on Pokémon with Regenerator and solid bulk, Stuff like Tangrowth and Slowking. There is also Trick Room, which is played sometimes. TR-Teams are usually bulky offensive, with Pokémon like Slowking or Cofagrigus to set Trick Room and a lot of strong Pokémon to attack. Other threats are weather Sweepers. With Ludicolo and Kabutops Rain is a very threatening play-style and it is hard to check these Pokémon. The most common playing-style on the Ladder is offensive. With Qwilfish, Ferroseed, and Accelgor there are a lot of good spikers. There are also plenty of spinblockers to make sure your hazards stay down such as Rotom and Spiritomb. Kabutops and Cryogonal are among the best spinners in the tier.
