I disagree. (Check my stats) pve players ruined PvP. The weekend warriors who wanted thorn, but never have stepped foot in the crucible. The pve players who didn't realize that this is not pve, so ducking alone isn't going to cut. You have to move. The enemy is moving. You can't find the mathematical movement sequence of a real player. Most pve don't really use split second decision making. Normally all enemies move & shoot the same. No pvpers haven't ruined Destiny because it's actually easier to go from PvP to PvE than from PvE to PvP. You can ask the majority of PvP players about "the improvements" of the crucible & the majority of them would rather have the circle faction days over the diamond. Once again, check my stats. I'm probably more logged hours in PvE than PvP, but I enjoy PvP just a lil more. Less repetition. (Please scour for grammar corrections; & run-ons: & sentence structure) 😱😁
