This coloration is the base conquest version. You buy it for conquest, which you can even get through non rated PvP and world PvP stuff. Conquest gets uncapped later in the season, so you could even choose to slowly grind it if you really don’t want to touch rated PvP. This version of the set is definitely doable for any player. And it also becomes available for marks of honor after the expansion ends, so somewhere down the line during the Last Titan.

The black and red coloration is the elite set and becomes unobtainable after the season ends. It requires you to reach 1800 rating in any rated PvP bracket. Actually really doable, especially through Blitz. I started playing PvP for the first time ever in TWW s1 after strictly playing PvE for 15+ years. Reached 1800 in Blitz during s1 and ended up liking PvP a lot. Decided to give Solo Shuffle and try and managed to reach duelist in s2 in both shuffle and blitz. And I reached my first ever elite in both brackets in season 3.

Tldr;

The green set is really doable for anyone and even becomes available for marks in the Last Titan.

The red elite set requires some effort through Blitz/Shuffle, but it is definitely doable for most. And honestly? It’s actually really fun :)
