Yes, you are entitled to play the game as you wish - as is everyone else. What you are talking about is something else again; you are forcing the way you play upon other people. If you don't like people forcing you to play the game their way, you can't expect other players to appreciate you forcing your chosen method of play onto them. The solution is actually very simple and was suggested some time ago. Bungie could make the game's strikelists accessible to players who wish to solo them. Problem solved.
