I bet there will still be plenty to grind for. They just will probably make max light level easier to attain like they did with the last updates. Hopefully the best gear is still very elusive.
majority of my friends i met playing Destiny on ps3 was due to grinding! i also do like the fact that they will be focusing more on PvE than PVP! i have only played a few games and fewer online! Destiny was the first PvP game i really ever played. mind you i can now hold my own, but i dont feel i should have to grind it out in PvP to get the better rewards compared to grinding it out in PvE!
I thrived for a long time in destiny without playing pvp. Most of the gear you earned through grinding pvp were best in pvp and the same can be said for pve gear.
I just remember people crying when I played on ps4 about the loot, then bungie was pretty much handing things out. It was so irritating. Then they would cry about what Xur offerred. I hated the idea of Xur , he was an exotic killer.
They killed exotics in general. It was too easy to get them and made them not very effective. I would much rather have some kick ass weapons that were irritatingly difficult to get. But make them an absolute beast. Like the Gally in year one. But I also know I am in the minority by wanting things like that.
