Krieg player here, Armiger?

Hello! I’m a Krieg player and I was wondering, should I get a armiger? I’m trying to do 2k points mass infantry with support, but since Krieg infantry can’t be bought in plastic right now due to the revamp, I was wondering from the professionals if I should get a armiger as a freeblade? And which one should I get if I should? I’m thinking about a Helverin to kill everything in the air, but the warglaive could make up for my lack of good melee. What are y’all thoughts?
