So, just getting back into this, in 4 tower runs I got my Frost Prime BP, and the full Mag Prime. Pretty happy with that, considering I got nothing of value due to a glitch in one of the survival runs. Frost Prime now in the oven, Mag Prime pieces are cooking and then I'll build Mag Prime.
The new damage system is taking me a bit to get used to for some reason, and the change in the levels displayed. Took me a while to realise that level 30 was high now, until I looked at the map and saw that the highest level area I could find was 35.
The codex system is awesome though, once you get all your scanning done. Knowing what weaknesses and drops enemies have is awesome. Gives you an edge in the late game to some extent, plus makes farming easier.
