New type of items (light-blue) and (purple)?

hello ,
Im new (played hellgate global)
I found a light blue item
and a purple “corrupted” if I remenber correctly
is it new ? and by the way , is there better drop in elite mode ? or even hardcore elite ? or just more rare mobs ?

Mythic and double-edged items were introduced with MP 2.0 (TCv4), so they’d seem new if you never played test center with Abyss.

Thank you !!!
