Email in: Wondering if I could get your advice on my 1750 list [Space Marines]

"Hello Kirby,

My name is NJ I have been playing 40k for a little while now but I am a total newbie when it comes to playing 40k competitively. I am trying to get into it it but it is hard finding a list I like. As before I was playing a ‘Nilla marines foot list. I have been told that the ‘Nilla codex can not make a competitive foot list and that if I want to do a foot army to do Loganwing. But Space wolves are my little brothers thing so I don’t want to take that from him. So I have been playing around with some builds with the ‘Nilla codex and here is what I came up with...

HQ:
Librarian: 100pt.
Null Zone, Avenger


Elites:
Dreadnought: 125pt.
(2) Twin-linked Autocannons

So what do you think?"

You can make competitive foot Mech Marines, they are just on bikes :P. BA also does foot well. SM does do the best generalised Mech though but I think you're losing their biggest advantage, MM Bunkers. I'd switch your Tactical squads to carrying MMs over Missile Launchers and drop their LasPlas Razorbacks for Rhinos. This saves you 80 points which you can put 4x HKMs on the Rhinos and Razorbacks, 2x combi-flamers on the Tacticals and camo cloaks on the Scouts (you should also have enough points for a Heavy Bolter or Missile Launcher on the scouts, too). You lose 2 LasPlas RBacks but your Tactical heavy weapon can now fire out of the Rhino and camp in midfield which is an important aspect of Mech Marines.

Otherwise a solid list! Some like Vt2 would suggest dropping the Devs to Predators which works fine as well but you're gaining 4 units from those 2 FoC slots as opposed to the 3 Preds which provides more targets and fire saturation.
