It's probably just stats inflation: older legendaries lower stats, newer legendaries higher stats.

If current epic boss plus armors wouldn't be better than older legendary, there wouldn't be much point to try to get to the plus armor. There are 10 possible 2-element combinations and 5 mono-elements (well, and then there's Kaleidoscopic), so upping the stats is the only way to make new armors atractive. (you wouldn't trade in your mobile every 1 or 2 years if no features were added.  See Steampowered as a 5 year old mobile phone... ;) )
