Do you think the raiding pace will continue as is or slow down?
Personally I would anticipate raiding participation to slow down dramatically once legendaries leave us in a few days.
Will those simply be replaced by non-legendaries, or will raid spawns also slow down?
A worthwhile change I would like to see is increasing the daily raid free pass to have a max stack of 7. Still only able to collect 1 a day, but if you hit the gym every day, you still have a decent number for raiding. Forcing myself to go do some raid, ANY raid is almost as wasteful as not using it at all.
