The good news is.....in Bungies weekly update this week they have had referenced the complaints about the lack of end game and are working out what to do.
Overall the biggest gripes I have are:
token system / milestone system removed the excitement of drops. Iet me get my nightfall drop when the boss dies, not 5 minutes later at Zavala.
Powerful engram system making evetyrhing that isn't a milestone seem pointless
4v4, team killing has got old real quick
Lack of variability in armour, I used to love grinding for perfect gear ( tier 12 builds) , that side is really dumbed down
easier way of getting kinetic mods than just playing the gunsmith lottery, that sucks but seems to be bungies idea of end game content
raid gear needs raid perks, I know Lee doesnt like this but it allows people to progress through the raid better, and sets you up for hard mode. Running normal a good few times to get raid gear to prepare for hard should be a prerequisite, not least because knowing the encounters in hard is so important. VoG oracle disrupters is the perfect example of raid gear done well , weapons still great outside the Raid but essential for doing the raid well
Im less bothered by fixed weapon rolls but do think the mod system needs expanding so you can change the burn but also add a new mod. Weapon mods are so lacking.
Im also less bothered by the mosh pit but really think Destiny needs to get on the overwatch/R6 style 'ranked seasons', just to give the crucible a point. Trials should defiantly have ranked player pools, make it accessible and fun to all
until
