Hell no im not happy. The whole change to master work cores should have never happened in the first place. To get the best powerful gear we need to do challenging activities like raids, etc. Personally when i do these activities i want to use the armor and weapons that have the best perks for me to be as effective as possible. With the lack of cores i cannot do this because I don't want to use them until I hit max lvl, and for me that is just frustrating. Decisions like this and the drip fed content is pushing me away from Destiny. I have 3000+ hours(lol alot of grinding which i used to enjoy) put into D1 and D2 and used to love this game, but i am finding harder and harder to log in. I Personally think if bungie put more effort into strikes, stories, etc. And less into all the ever verse crap it may help.
