I don't honestly see where the beef is. I mean, seriously, you are saying that PvP players are being badly-done-by because people who don't want to be "content" for PvP players are able to play the game. So the complaint is that you can't be allowed free reign to engage in non-consensual PvP with everyone and anyone who plays the game?
To paraphrase part of your post: "casual gamers who wont have the gear of more invested PvP'ers and end up getting slaughtered for it".
Maybe what is really needed are more PvP-only Private Groups or is that anathema because there won't be any non-engineered-to-the-max player's ships to be cannon-fodder?
I don't have a "beef" and I think you've misunderstood my post and its point.
I think mixed PvE / PvP games are a bad idea, because it's generally the PvP'ers who get the short stick in them.
So I understand their frustrations and complaints. You cannot make a game for two very different groups of players and expect it to just work out.
Aside from having their game play style neutered and limited, being pushed away from the main game in most cases.
Once a game is established then anyone new finds it really hard to join PvP due to being constantly under geared to those who've been there from the start.
This was an issue in Star Trek Online until they removed PvP specific gear and now you can PvP in gear you earn elsewhere. You just have to learn decent gear combos.
However Warframe still has PvP specific gear, so they still have this issue. So PvP gets little Dev time or consideration (again, short end of the stick for PvP).
What PvP'ers need, is a game built for PvP that isn't just a re-hash of Battle Royal or Team Death Match.
Something that rewards PvP, has objectives / goals to work towards and doesn't stop new folks joining in.
I hope Star Citizen helps fill this gap in the gaming market, as it seems to be more aimed at PvP game play (from what I can tell - I could be wrong).
Hope I've explained it better.
