Warhammer 40K Tabletop XVI: "Terminator? I hardly know 'er!"

[Cheesegear]

any more reccomendations? I'd like to include dreadnoughts because dreads are cool but am not really sure what to buy more.

You need an Emperor's Champion, and he can not be the Warlord. So you will also need a Captain model. If you want to run large squads in Land Raiders, you can get a Chaplain instead.

Terminators with dual Cyclones.
Since you have no Flyers of your own, you are actually going to need some Dreads; Twin-Linked Lascannon, Missile Launcher and Tank Hunters. Venerable Dreads cost the same currency-wise so make them Venerable, because it is cheap.
You also wouldn't go far wrong getting an Aegis Defense Line either.

Crusaders in Land Raiders. Otherwise Rhinos. Black Templars can take minimum 5-man squads with Meltagun and Multi-Melta, you can stick them in Rhinos if you want to - you should.

Land Speeder Tyhpoons are still the only decent Fast Attack choice.

Due to complete lack of Devastators and your Dreadnoughts and Terminators being on Anti-Flyer duty so grab a Predator or two. And, of course, Vindicators are fairly good so it's worth getting one if you're facing a lot of FNP.
