Already covered the question of running Templarish lists using the SM Codex for my own personal reasons so not necessary to go into that again.
My question to you experienced 5th Ed Marine players is more along the lines of Heavy Weapons and Devestator squads.
I play a shooty anti-personnel army. Honestly it's not much good against armor, and I know that. My anti-armor choices are my Ven Dred with a multi-melta, then I also have a ML in each of 2 tac squads, along with a lazcannon in one of the tac-squads, and a plasma gun in the other. My Dev squad is running 4 Heavy Bolters because I like to mow-down troops.
So I guess my question is, am I shooting my-self in the foot so to speak running a list like this? Also, what kind of "quick" adjustments could I make to take on armored/mobile armies and keep my 1500 point range in check.
I don't play tournies so I'm not concerned with fielding 1850 or greater.
Thanks again Btown!
