Hmm, this looks like an improved CA, regarding the stats.
IMO 35 normal DR is enough, CA should always stay better against normal, and 40 fire dr is enough aswell, 50 is BoS wtf.
The metal armor mk2 has 30 dr, +5% dr is a good upgrade already.

There is a mistake in the wiki btw, it displays normal 4/35%, but ingame it's 3/30%, only the helmet has 4/35%.
