Changing Area Influence In The Past.

How long would it take a duo to change the influence of a particular area in the past? I'm thinking of castle ostrozja(s), I know people used to do this w/o tags on when everyone was trying to get the Shadow Lord BCNM opened up. What is the fastest way to go about doing this and what other ways besides fighting campaign mobs w/o tags can you use? Specific OPs ?

Anyone?

well for the lord fight it took like 50-100 jps spamming those zones for last coupe days of a tally. This when it first came out of course.

What do you need to get from the past Draylo?
Just finishing camp out or?

I just wanna do the yagudo bcnm for fun and if roundel drops at all.

I think all you need to do is kill mobs without tags on from about ~3am EST until JP midnight on tally day. I don't think there's anything else that can be done.

see i was under the impression it was doing campain in the zoen to take control.
