502 4set worth it?

[Kreger]

I'm currently dw frost 521 ilvl equipped, just got 502 t helm/shoulders today and was wondering if switching to the 4set from my 522 shoulders, 516 helm is a dps loss, or will it stay the same?

If I remember correctly the 4p for DK's is pretty weak this tier. The huge loss in strength and gems from switching out a 522 shoulder and 516 helm for 502 gear isn't worth the trade off.

Like demonstrated here : http://www.mmo-champion.com/threads/1322495-4p-worth-it, it's not worth loosing so much stats.
2 set is however like Vereesa explained to me not breakable at this point of the game.
