I've played my fair share and I understand the need for making things eventually obsolete but do to there being only one way to achieve max lvl they are really bottle necking player diversity and making things to easy with the vanguard and crucible gear bringing you to a level that you can skip right to the end game content without putting in the effort in the pre-expansion content . While most MMO style games make you work your way through old content to reach new content. In all honesty I've never seen a MMO style game let players skip to end game content so fast before in all its a bad decision on Bungies/Activisions part letting people have an easy way to end game content because we all know MMO style games are all a bit grindy but destiny is pretty high up there in the grind fest and when an easy way out is given people will take it thus shortening game play time which lowers player investment and with less invested players are more willing to quit playing.
