sure it does, it completely nullifies the importance of teamwork and strategy when anyone can glitch / cheese / exploit their way through content and earn free loot. it lowers the value of every single person with raid gear equipped, as you have no idea whether they earned that gear through hard work, sweat blood & tears, or by watching a youtube video and exploiting a poorly designed game.
completely de-values the raid gear.
how can you not understand that???
It doesn't effect you though.
Nothing of what you have said effects you or anyone else at all.
The only thing that has devalued any gear is Bungie giving scrubs the chance to be 31 off the bat without ever having to complete the VOG.
Someone un checking their network option to short cut a not particularly fun boss isn't harming you or anyone else.
