Can please explain how solo players can participate in raids?

i think as long as you show up and you have a pass your ok. I think I read somewhere that for raids you don't even have to be in the same team.

I think public groups should be the norm. Someone here suggests it would require at least 5 people to take down a raid boss, I don't think many players can form a private group of 5 on a regular basis

I think this private groups are for mass events, because only 20 players can attack at once

As you can read, we 'think' no one knows! , no one can know these answers, everyone has to wait...
