Good choice getting into
BT
Seems like a good list for the points, the
LRC it's expensive but it's hard to bring down and the Twin
AC with 12 Bolters adds good firepower to a
CC squad inside.
Seems like in 8th edition we rely more on buffs from Characters, having less
CC attacks and no Chapter Tactics, but said buffs are within 6" and having multiple
CC squads would lose the effect, hence an
LRC it's a good way to keep the core of your list together and strong at any point level.
Devastators are good but not very fluffy depending to whom you ask, you can use our Crusader Squad strong points instead and have 1 Heavy, 1 Special + Sergeant list in 5 man squad, and now you can put two of those in a Rhino!
I suggest you get our
HQs asap, the
EC is a beast and always been my MVP, Helbrecht seems essential now to buff up that
LRC Squad.
Edit: Looking into your list Helbrecht it's only slightly more expensive than your Captain at 170pts, totally worth it, I'd also add Plasma Pistols to your
SB for 7pts and take Axes instead unless you have the buff from the High Marshall then Sword are good at S5.
