[Why does no one play conclave]

Warframe is mainly a PvE coop game. Look at how much DE has invested in PvE vs PvP. They only added it to "appease" people that love PvP. People dont come to Warframe to PvP. Plain and simple. Dont get me wrong, I am not against it, I just wont ever play it because....well frankly, I dont care for it.
