I know u cant do the cms anymore but can u get same model for it somehow or am i sucky and late

In Legion they introduce many recolor versions of the now discontinued challenge mode sets. This means that the old sets will still be unique, as that color is unobtainable.
But there will be new obtainable sets using the same models, just in different color variations.

Here's an example of one of the recolored sets for Paladin

Well neat i like it
U know how to obtain that 1

These are sets that have been found in the beta build of Legion, but I'm not sure if Blizzard has officially stated where you get them, yet.
From what I understand through Wowhead most of them are obtained via the Order Halls (which are replacing the Garrisons).

You can see some of the other challenge mode recolors for the other classes, here: http://www.wowhead.com/news=252682/legion-order-hall-armor-videos-battle-pet-updates-and-new-corgi-suramar-interior#order-hall-armor-videos

There is also a red recolor, which you can see here:

How do i get the red recolor

From what I was able to find it seems like the sets are linked with the new Order Hall, but I'm quite certain that it hasn't been disclosed yet exactly how you get the recolored pieces/sets.
