Since all armors decay the same now compared to the protection they actually offer against mobs id say slightly higher than animal series if your dealing with a mob that does almost exclusively cut but otherwise about the same "in total" yup. Especially with 5B like Mike said which makes paradox into one hell of a versatile armor compared to what tiger, angel etc costs... especially with mobs that do alot of cut (big trox, etc).
And especially the thighs are rare as f*ck... i doubt even 10 were looted total ingame unless someone is hiding a dirtload of em in storage somewhere
Also gloves seemed to only drop for a few days from aurli then that was over..
So yes some of the parts are truly rare.. last sale i know of (paradox male) was something like +7k for full set, and last thighs i know of that sold went for +4k... Both a while ago.
If these sets followed inflation like everything else ingame then slightly more now... Id say 8-10k for full male and wont say anything on female since i have one of the very few sets there is (dont really want any accusations of trying to boost price etc...)
And from what i know there are indeed about 4-5 "completed" male and 2(?) female ingame + some parts that might make a few more sets if gathered, impossible to be sure..
Theres another thread going under "Buying" part of forums that "Pikachu" started... Might be some more info for you there.
