most of bungie is almost certainly working on destiny 2, some people will rotate into HoW/comet as needed but its one or the other. I doubt they have multiple teams, very inefficient since there will be lots of downtime in D2 as they prototype stuff and designers iterate and lots of downtime on Destiny as QA tests stuff
Problem is, who the fuck will buy Destiny 2 after the mess of things they have made in Destiny?
Dont get me wrong, I love the gameplay but it seems they screwed up every single other thing that is in the game;
*Storage space
*The billion diffrent currency system
*No random instances
*Slow as fuck release of content patches (yeah its not a fucking DLC if you include 40 min of missions then throw in a raid, its a PATCH)
*RNG loot without enough chances to get to roll the RNG
*Missing in-game match making for raids (they claim the raids are "too hard" for randoms to do, thats why everyone is throwing together random groups though private forums.....)
*Building the PvE game around 2 weapons of which one is RNG and the other is frequently for sale at the weekend vendor
*No custom looks for anything, every fucking player is a clone of every other of that class
I could go on but lets not. Simply put they would have needed to hire some guy with actual experience for a RNG loot game for this from start.
They have not had a PvE event since what, the 1st month of the game? Its the same old tired fucking PvP event that rolls around. Something is seriously wrong with their project management or higher up in the chain, a IP that you have poured this much cash into and so much prestige should under no circumstances be handled this way.
