Praetorian invasion schedule
It seems that the Preatorian invasion indicated for May for City of Heroes has a more detailed schedule than just between May 11th and May 27th – it runs only on specific times on each server.
The good part here could be that they are maybe running it with real people behind the scenes; at least that is the only explanation I can see for these specific times. The bad part is of course if you cannot make any of the times, then you you will miss the whole thing.
For me the only time I may be able to catch a bit of it is for my main server, Defiant. It would have been nice with perhaps multiple times on each of the servers. Anyway, if you are interested in participating in the event, check out the times and if anything fits your schedule.
