As Space Marine variants make up the majority of armies in Warhammer 40,000, it is generally wise to build your army assuming you will fight them at some point. Many of the units that were good at killing Space Marines still are. Brôkhyr Thunderkyn, Doomsday Arks, Howling Banshees, Riptides, and Knight Despoilers will continue to cause problems for the Adeptus Astartes. So, having broken down what the impacts are, what are the advantages of this change for you? As we’ve said, there will be fewer Space Marine corps on the battlefield, which will change the way they approach the game. They won’t be able to trade** for objectives as well as many non-Space Marine armies, and will have a harder time holding objectives and reaching secondary objectives safely. More horde-focused armies like Astra Militarum, Drukhari, and Genestealer Cults will be better equipped to trade bodies for the brutal meat grinder and achieve that sweet victory. The strength boost of bolters and chainswords has varying degrees of value against your armies. For the average human, Aeldari, Leman Russ, or Goliath Rock Grinder, this change means nothing, as it is not enough to improve their wound chances against these types of targets.
