in regards to the issue of there being far less of a grind and things being easy, I have a feeling that those things will change over time. Things like difficulty in activities is a thing I see coming for sure. The problem is is we, as the more hardcore segment of the base find these things to be easy because we know how to play a destiny game. A lot of the initial players playing now, don't. So as the weeks go by, and more content is added, I would assume different levels of difficulty, modifiers, etc. will be added. I mean even something like the Nightfall currently isn't crazy super hard for players like us, though not "easy", but again, for the vast majority that may be one of the tougher things they ever played (yes some hyperbole there).
Also, I would shocked if there wasn't more things added to grind for, what they are I have no clue, but do we even know something like what the drops/rates are for something like strike gear, which is exclusive to the strike? Things like that are an easy grind to add right there.
And I think they are trying to change the grind from a power game, where it's all about getting to max PL, to something a little more Diablo like, where the grind so to speak is to find gear, weapons, mods, etc. Which was always part of the game, I know, but I feel like they are trying to put more of an emphasis on it then before.
At the end of the day who knows? I'm loving it so far, and I feel like with high moon and the other studios working on D2 in addition to Bungie, that content, even things like gear, weapons, and stuff will be a lot more frequent. I know we were all wrong about that in the past, but they made so many corrections to things, and they must know that even something like adding a raft of new gear every couple weeks would be enough to get people to chase it.
