Yes - loadout, determination, effort. I put those into PvE. I do not put them into PvP. I do my 10-12 Crucible matches a week to get marks like I am punching a clock. I don't switch weapons, I bring whatever I equip for daily heroic or strikes. Others do the opposite (focus on PvP) or do both. That is fine, but it is not the same as skill.
