Your list is not a good list for the following reasons:
- Your chapter master costs almost the same as Pedro Kantor while not having Pedro awesome buff. You either choose a named character as
HQ or stick to a cheap captain/librarian. At 1500 pts, one librarian with bolt pistol is the best option.
- There is no reason to ever take Tactical Terminators. Thunder hammer and stormshield terminators or leave them at home. You might think that Drop Pod goes down turn 1 with Dreadnought, then turn 2 Termies come in shooting. The problem is they don't come in turn 2 all the time. That dreadnought (and probably drop pod) will be dead on the enemy turn and 10 Str4 shots cannot kill anything.
- If your dreadnought is going to go down in the Drop Pod, take multi-melta, it will kill as good as (or even better) than
TLLC and it is free.
-
Tac squad is all around bad choice for
SM. There are only two ways to take tactical marines for
SM: 5-man with Razorback LasPlas or 10-man with upgrades. So that 8-man squad needs to be changed. You will find that sergents power fist will almost never see any use. Those powerfists and Melta Bomb might as well be used to buy Typhoon Landspeeders or Riflmandreads.
At 1500 pts, there is not many choices for
SM that will be competitive, check out this compilation of different lists that work
