Only gripe with bo7 is there is no map with elemental WWs

I want to get kitted out with the boys and watch multiple colours of bullshit annihilate the hordes

Rex was the perfect chance for this, 1 elemental upgrade per shadowsmith. Have the upgrade be loosely based on the WW for that map (have the WW for that map get dismantled during the respective upgrade quest, like u take a spike from the necrofluid gauntlet, the spinny disk from the LGM etc)

Bo7 overall was damn near perfect, its sitting around the same level as bo4 which is only slightly behind bo3 for me. Rex could've sealed the deal with a peak finale map with elemental WWs
