How are your terminators going to be teleporting in? Unlike
40k they don't get it baseline, and from what I remember Blood Angels don't get access to Teleporter Transponders like the Imperial Fists do. Also you seem low on anti-tank.
My personal take on this would be something similar to:
HQ:
Legion Praetor: Cataphractii Terminator Armour with Combi-bolter and Power Weapon, Digital Lasers, Grenade Harness, Mastercraft a Single Weapon, Paragon Blade
·· Legion Terminator Command Squad: Cataphractii Terminator Armour with Combi-bolter and Power Weapon, 4x Chainfist, 3x Legion Space Marine Chosen, Legion Standard Bearer
Troops:
Legion Tactical Support Squad: 7x Legion Space Marines
·· Entire Squad may exchange their Flamers for:: Flamer
·· Legion Sergeant: Artificer Armour, Bolt Pistol, Melta Bombs
3x Legion Veteran Tactical Squad: 9x Legion Veteran Space Marines, Veteran Tactics: Marksmen
·· Additional Wargear: Heavy Flamer, Melta Bombs
·· Legion Rhino Armoured Carrier: Iliastus Pattern Assault Cannon
·· Legion Veteran Sergeant: Artificer Armour, Bolt Pistol, Bolter, Chainsword/Combat Blade
Fast Attack:
2x Anvillus Pattern Dreadclaw Drop Pod: Frag Assault Launchers
(Support Squad and Terminators go in one each)
Legion Land Speeder Squadron
·· Legion Land Speeder: Graviton Gun, Multi-melta
·· Legion Land Speeder: Graviton Gun, Multi-melta
Heavy Support:
Legion Artillery Tank Squadron: Legion Medusa
2x Leviathan Siege Dreadnought Talon
·· Leviathan Siege Dreadnought: Armoured Ceramite, Cyclonic Melta Lance, Heavy Flamer, Heavy Flamer, Leviathan Siege Drill, Phosphex Discharger
Atleast in my opinion, it's your list end of the day
