PvP is meant to be a side attraction — is that your opinion? Or is that an official statement from Bungie?
Because for me, and for many others I know, it's the main attraction. Remove PvP and I'll no longer play Destiny, and many others will also leave.
Since day one, Destiny has had PvP. It's an integral part of the game. It should be improved, not ditched.
Finally, "lack of skill gap" in PvP is an opinion. "Skill" is subjective, but most players agree, the skill gap has gone up, not down. I've played other shooters, and Destiny is no more or less "skillful" than they are.
