Ugh, so this is complete BS.
I joined my buddies who were at the final boss of the Riad and helped them finish. I got the Chatterwhite shader and that was it.
Now I played through again and I am not able to get anything apparently? Since it is counting that I already beat it I am not earning any rewards after we beat each section... even though I haven't beaten those parts yet this week. That is bullshit. It should count each part beaten per week, not just the Raid as a whole. I think that is BS that you can't farm the Raid more than once anyway. It isnt like it is super easy to plow through and will be done super quickly by everyone. To me the Raid is the most fun thing in the game but since it doesnt tie to bounties and it doesnt tie to any other real ways of gaining anything other than some XP for your gear it isnt worth it. It is more beneficial for me to play a bunch of control matches alone than it is to play the Raid again. As if the loot system didnt suck already. Did they ever say why exactly you cant do it more than once a week?
