Hey, i just recently got back in to 40k and am wondering about lists. Just want some input as to where this list could be changed, since i don't know whats good/bad in this edition. I know i have a low model count, but i mostly play other players with low model counts as well at the moment. I just want to know if there are any major flaws with the list in general and in relation to the 5th edition.

Was thinking id keep the grandmaster and retinue in a LR to start, and move in once my troops have made their way into assault.
