Editing List of 40K Cheese (section)

===Space Marines===
*Eradicators: New special sue marines who carry 24" melta rifles that can fire twice if they don't advance. They are infantry, so they can benefit from that keyword, and can get in the Primary Stu transports, and to add insult to injury are literally Fire Dragons but better, which rubs Eldar players the wrong way. Oh don't forget your captain and Lieutenant to buff your suicide shooty unit, just to make sure those hits come through.
**Salamanders: Your eradicators wound even knights and thunderhawks on at least 3's, reroll a single wound roll per unit shooting, and with a captain and lieutenant you're guaranteed to nuke just about everything in the game.

*Dark Angels: Especially with Ravenwing Chief Apothecaries, Talon Masters, 4-damage Plasma Incinerator Redemptor Dreadnoughts, and permanently transhuman Deathwing Terminators.

*Black Templars funnily enough had a very brief period where they could field Crusader Squads for cheaper than Tactical squads. However, as this went away with the supplement's release, this is a "middle" tier cheese at best.

*Armour of Contempt: Dear fucking god, this rule. Introduced with the quarterly balance dataslates, this rule makes ALL Space Marines (as well as the Sisters of Battle, CSM, and Imperial Guard <s>Leman Russes</s> VEHICLES) reduce the AP of any attack they suffer by 1 unless they're equipped with a Storm Shield. Now, while the Sisters and Guard tanks did need some extra protection, being respectively merely T3 1W models protected by only a 3+ save and fairly fragile without baked in Invuln saves, this was glaringly egregious on every flavor of Space Marine, especially now that they were T4 with minimum two wounds each. This made even mainstay anti-marine weapons like plasma guns worth less now that the once valuable AP-2 would only make them roll a 4+ save and made any number of AP-1 weapons pointless. Needless to say, that with the typically ubiquitous number of marine players out there, this will annoy you to no end.
**It wasn't until the Q1 2023 dataslate that the writers realized how much of a drag this rule became, as it was summarily scrubbed from existence. This means that the arms race to beat this utterly busted rule has drastically slowed down...with the exception of the Leagues, who have this built into their codex.
** The most frustrating part of this debacle is that spess mehreens legitimately did need a significant buff, being a peasant-tier army for almost all of 9th.  But fucking over every army that's built around AP-1 attacks because GW couldn't get the balance remotely right the first time was an incredibly fail way to go about it.
