Meh, Bungie doesn't really understand how to make a lasting online game and it shows from this expansion and vanilla Destiny (they're treating it like a run of the mill shooter). Sadly I think this is what we'll be getting in the next dlc as well.
Well I was wrong on the Heroic weeklies since this weeks was the new strike it locked me out of it but now that I unlocked it we can still do it for coins but only 6 since the last difficulty level is 30 and that will be hard as 29's. Though with as stupid as we are I'm sure 30 will be what we do (because we all love a challenge). I'll note this that it seems a lot of the enemies for this dlc have arc shields so having arc weapons will be key it seems for everything that deals with this one (I mean the end boss for the new earth strike has arc shields by the looks of it (and this means Hive, I have no idea what shielding types the other strike has but considering they're Vex enemies I'm assuming Void as well as Arc).
