Why? Grimaldus got significantly cheaper, our chapter tactics put us on par with other assault based chapters. Our characters are allowed in formations, but our crusader squads aren't. Our Emperor's Champion is back to being full Beast mode again now that they nixed the silly stances and just gave us str6 w/ instant death. We still have obsec land raider crusaders. There's now a Land Raider formation that ignores crew shaken and stunned results, and gives us an edge when fighting super heavies. There's even a White Dwarf with Black Templar specific warlord traits, one of which gives us some anti-psyker tech. I'm pleased over all with the changes to BT.
