List is looking good, altough i would give
BP to death company, you want to chop stuff up with them, not shoot (10 more attacks in
CC is better than5 extra shots
IMO)
Also drop out plasma pistols on assault squad, 15 pts for weapon that can kill you isn't worth it, and tactical sargeant with powerfist is probably gonna get killed before he strikes back,also powerfist isn't gonna allow you to kill what you already can't.
So i would give death company boltpistols, 2 powerweapons(prefferably axes if you encounter
TEQ-S) from the points you get when you remove plasma pistols on assault squad and powerfist from tactical squad, give it to
DC and give that one guy a bolter, because it is specialist weapon... Also, try to give the assault sargeant with
LC a
th/
ss loadout, he will do lot better in challenges...
For a friendly game, your list seems fine, for competitive play you need to tweak out loadout in between characters
