my POV is bungie doesnt have enough time to complete the development for the new raid. they cant keep the player to wait further and thus decided to launch without a new raid. IMHO, it's better for them to fix the annoying bugs in VOG and CE rather to release a half baked software. They boasted too much on HoW and end up setting very high expectation among the community. In short, they over promised and this is definitely no good for business.
Sora, I dont mind to grind the POE provided that it's fun and the loots are promising. Otherwise, i gonna spend my time for other stuff then. will see how it goes then. I believed many veteran players are cursing Bungie now. 

LOL. Never mind, gotten those two expansion packs(The House of Wolves and the other one about Crota). Can't seem to get a damn primary legendary weapon! Only gotten 2 legendary for special weapons(Murmur and Vestian Dynasty) and The Fear(rocket laucher).

Anyone in here knows how to get good legendary primary weapon?

I completely have no idea what you just said but let's go with it. Can't find any. Even in Crucible... 

The add-on has to be from US R1 as well. So you cannot but MY R3 to add-on to R1 destiny.

You can buy the whole legendary edition TTK from MY PSN (which is possibly cheaper than US TTK add-on alone), and then use your US psn account to login and continue playing.
