It isn't too bad at all. I would definitely suggest writing lists to see where you to go, though this assumes you haven't models already.
In fact I would suggest writing 1500 points instead as it is easier to make a balanced list.
Also read your
FAQ off the
GW website.
librarian is good set up.[ but can only foot slog, drop pod or landraider around, which is an obvious limitation when thinking about lists in general.]
Tactical squad really doesn't want a fist, the serg. is bound to called out for a challenge where he can die before hitting back. In fact I would go bolter+pistol, if you get into
cc: try to lose combat and then combat tactic out of there and regroup and rapid fire the offending unit.
Then really need some form of transportation.
Scout squad is an awesome set up.
Terminators are all right. Their weapons are really short ranged. I have to assume you plan to gate them around, which is a reasonable idea. Shooty terminators are a good choice at lower points as they are flexible and it is hard for the enemy to deal with. Higher points these guys should be gathering dust I am afraid.
The other point to mention is that deathwing allies would be better.
Dreadnought again is a little short ranged, it should be all right at low points as tables tend to be smaller. If not give it a drop pod, if drop podding I would usually prefer a
MM but assault cannons are cool.
Techmarines have different bolster ruin rules right now !?!
Point this out to anyone you're playing or disagrees.
They are not worth it. They can be made to work, but that is a dull topic. I would maybe even take one as an ally instead.
The exception is the thunderfire cannon which is cool, also Master of the forge is a
HQ that can be useful.
Techmarine on a bike can be vaguely useful, this gives a strange boost to biker squads.
Techmarine with servitors can be a strange but effective unit to put in a landraider, though this more of a joke than anything.
Next thing I would buy is a razorback. They sit with dreads well, in a slow rolling mech wall. You marines deserve this.
This would be better than a techmarine, for example.
If you could save 85 points then an
ADL with some gun would be worth it, you can hide behind it and shoot things. Drop fist and a couple of scouts.
I would prefer 2TLautocannon dread but that is mostly just about range.
Hopefully some of that was useful
