Wonder if guild leaders will evetually get to go into battle flying a banner with their guilds heraldry on it. Dunno if that works with marines though since they have standard bearers instead of a flag on their back. New guild related melee class? The standard bearer. Uses the flag to beat people to death just like in classic halo maybe?
Actually they'd have either a pistol or melee weapon in their offhand. Preferably the ability to maglock either weapon and switch between pistol and melee. https://www.forgeworld.co.uk/en-US/Space-Marine-MKIV-Command-Set?_requestid=6449886 And FYI these types of standards can be done in 3rd person games without totally obscuring your view. There are flag/standard bearers in Mount and Blade Warband/Napoleonic and you're view isn't blocked any more than the full left 1/3 of your screen that's blocked when you use a Heavy Bolter(that's NOT deployed) on a Devastator.
I'd rock a Standard in one hand and a shield in the other in a heartbeat. That'd be my loadout of choice, if I could take it.
Oi, we need dis! 'Ow else is da gobs wot got stopped s'posed ta know it were Da Gobstoppaz wot stopped'em?
