So when i first made the post it was just going to be about asking for more chain weapons, as having only the base chain sword kinda blows. Then i realized, What about the other amazing melee weapons. 

This left me with two questions. 

What restrictions on possible weapons are there from a gameplay perspective? 

(for ex. no two handed weapons for any other class then assault? only power weapons for the melee classes?)

As well as what lore restrictions there are?

(No chain axes or lightning claws as theyre not common to find among loyalist space marines?)

I figured the best way for both parties, you, the devs (hopefully) and us the players, to get what they want would be some kind of poll for the playerbase could vote for what weapons and or other additions they wanted in the game. League of legends has done this with reworks to some success. 

On a finishing note, is there a slight chance of seeing power spears in the game? 

I know theyre not really common at all in 40k, but i think theyre as cool as the other more mainstream weapons, and would be far more uniqe from a gameplay perspective. 

While a poweraxe or something more common would be awesome, I really think a power spear would add a more unique playstyle and moveset with more possibilities for unique mechanics.

Raven Guard utilizes lightning claws often. 

They're the single weapon I've wanted to see in action the most. 

I want the flamer. The HEAVY flamer.
