A minor recommendation, but for us blood angels players who are having to wait forever for our cosmetic content, this would be a huge boon. It would also be good for everyone else who plays assault regularly.

Firstly, the lore/TT argument:

1. Inferno Pistols are a BA specific weapon both in table top and in lore. BA are very closely tied to the assault marines as a chapter identity. For those of us who play blood angels, being able to take an Inferno Pistol as assault would be a great way to get more in character and immersed in the game, and at least for me, would tide us over until our cosmetics come
   
2. On the table top the majority of units that can take inferno pistols are jump pack and melee units in 10th, the only real exceptions to this are tactical marines and Death Company with Bolt Rifles, who are a BA specific unit. Notably none of the units that can take inferno pistols are in phobos or gravis armor (sniper, heavy, vanguard, the classes that actually got the inferno pistol). While I don't mind Saber branching out and getting creative, not giving the inferno pistol to a class that it is most iconic with, while giving it to classes who it has never been seen with, rubs the wrong way.

Space Marine 2 is hardly a 100% lore accurate game when it comes to loadouts, and i'm not saying we should strip heavy and sniper of their inferno pistols, I just want it given to the class it is most ironically tied with.
Second, the gameplay argument:

1. Inferno pistol does fill a niche for assault: instant close range damage. It's not like giving inferno pistol to assault would be superfluous, though it likely wouldn't be the best strat it would be a unique playstyle that very much leans into assault's core gameplay of being up close and sustaining melee damage.
2. Assault lacks a primary, currently most of his unique gameplay comes from which melee you select, adding inferno pistol would give him a new layer of playstyle dimension, as it would force him to always engage to get the most out of his gear
   

All of assaults secondary's are very similar in core design, giving him an inferno pistol would offer him a new, unique playstyle that isn't entirely reliant on which melee weapon he chooses.

At the end of the day I love this game, and patch 7 seems great so far. Most of the cosmetics slap, adding more shoulders with blank faces for decals is a great choice, and the reworked melee perks are really good. This is all that is on my wish list. BA players are already waiting an eternity for our cosmetic content, we would love it if you could throw us this bone.
