What kind of loot will we be getting from a kill? I mean an eldar would not be lugging around apart of space marine power armour and no self-respecting space marine would use a bolter from a traitor marine... So would we be getting loot or just gold or other useful material that we can craft in to armour and what not?
i would guess that you would loot nothing from enemy players maybe you could find some "loot" in a tyranid dungeon
I don't think you loot enemy PCs and the Underworlds what have minions/bosses dropping loot. You won't be digging around inside a Tyranid's stomach for a master crafted force sword +1 or anything like that. You will receive rewards for helping the war effort by doing the Underworlds and there isn't going to be crafting as such, more like BF3 where you can add attachments and things onto your weapons and armour. I'll try and find all the sources for all this, bit difficult as I'm in work atm
I really hope you don't fight off a Nids invasion in PvE and it's like every other mmo going "oh here's shoulder pads he was holding on to for this race/class/archtype for unknown reasons". I hope it's more like obtaining materials or plans and bringing it to a Techmarine/Bonesinger/BigMek/Warpsmith to construct the parts needed. Once you have enough of each part as per a set of plans you can create new weapons or armor or use the parts to just upgrade existing pieces you have, using it like slotted items.
There won't be loot like that. Now will you need to haul around raw materials to craft into something later. You will earn requisition, that can be used to equip your loadout. Also, participating in the PVE will sometimes net you gear, but it will be from boxes/crates reliquaries or other things that make sense, not an iron halo that was eaten by a carnifex.
