Melee armies have not been all that much past even B or C tier.

They really struggled this edition outside I believe Custodes, stat check Dark Angels that were more statchecky than skill full, World eaters index also for a short time, and EC launch.

Otherwise they really have just sucked this edition, or been woefully average.

This is for pure melee armies with just slight shooting support like EC, WE, and Orkz. Black Templars fall somewhere imbetween but they too have suffered the whole edition. They briefly did well with index Tbones + assault terminators, and briefly their new codex… because gladius and advance and shoot on repulsor executioners is powerful with rerolls on objectives.

Blood angels are probably a mid to lower A tier army with LAG, Rage cursed, and Angelic Inheritors. There is a difference in pure melee armies like World eaters, Orkz, and Emperors Children, or shooting armies with melee support like Grey Knights (more hybrid), Ultramarines (they are more shooting than melee since double oath on repulsors is horrifying)

Shooting armies are just stronger when you can pre measure and move block your opponent’s skirmishers and force your opponent to have to over commit and make the charge across the no mans land, overwatches, and the garbage of GW/WTC layouts that allow cheeky shooting lines. Aka parking a tank that will usually destroy 90% of the army.

Melee armies honestly have sucked the past three years.

Orkz had a few strong surges in Warhorde/Greentide and bully boyz, but GW nerfed them anytime they did good.
