Already patched for 1.6 bugs:
-Proximity mines armour not working for the Legion Techmarine. Fixed.
-Possessed Tooltips. Fixed.
-Deathwatch Squad for the Grey Knights and SM armies. This is a very versatile tactical squad. Akin to Sternguard, but instead of combi weapons they gain access to special heavy weapons and Vortex Grenades.
-Primaris Intercessor Squad for Space Marines. These are basically a long ranged tactical squad that forgoes heavy and special weapons for extra range and durability. Can take Stalker Bolters or Auto bolt rifles, which have shorter range but better rate of fire.
-Primaris Hellblaster Squad for Space Marines. Similar to Intercessors, but these come with the Plasma Incinerator,a longer ranged plasma gun variant. They can replace them with Assault Incinerators, which have greater AOE but fire at shorter range, and Heavy Incinerators, which are basically plasma cannons.
-Primaris Reavers (No I'm not using the retarded GW spelling) are a harassment melee unit with Stealth. They have rapid fire bolt pistols, power knives and blind grenades, as well as a paralyzing scream ability that debilitates enemies.
-New Warp Talon squad for all CSM at the Chaos Shrine.
-Tempest and Implosion Bolter shells for Deathwatch.
