Thoughts on Terminus Warrant in h40?
Thinking about something like this with Bolter and Maul+Shield. For the last two talentpoints there is the 10% ranged dmg node, Prosecution Blow (20% rending on crits) or some of the defensive nodes at the top. Maybe cut BTL nodes for True Grit and something else on lower right.

I'm worried about ammo efficency. I'm thinking the playstyle is to mostly ingore Melee Justice and stick to Melee but change to your Bolter for Ogryn packs and Bosses and benefit from the ultra fast reloads.
