Thank you for your feedback Skitarri! I found it really helpful
I honestly don't think that I'll be able to free up enough points to get Kurov's Aquila for my Commander, although I could get more anti-monster & long ranged anti-tank firepower.
In light of your suggestions I thought instead of a full squad of Lascannon Sentinels I should take a Vendetta gunship (only 20 pts more for a bunch of Twin-Linked Lascannons)?
To deal with monstrous creatures I could take a Leman Russ Exterminator for the Exterminator Autocannon, with a Lascannon and Multi-melta sponsons so it's versatile enough to attack both monstrous creatures and armour...
This is what I'd have
