In the end, it is up to the guild master to make this work. Not me, not anybody else.
That being said, personally, I don’t think the guild concept works very well in WoW. There are so many things that will work against you.
I had this idea. We should rally a lot of people. There will be a massive uproar, a… You could say, citizen congress…
You’re right, a protest can be organized without involvement of other players (it might be a bad protest if it ends up happening on random evening where there are no guard RPers in Stormwind because nobody besides OP knew about it beforehand, but it can happen).
Infiltration, spying, sabotage and other similar activities can’t, which seems to be something OP doesn’t realize. The feel I get from them is that they’re a new RPer who doesn’t quite know how things happen on this server (given their response to people asking what their OOC plans are involves repeating the IC plans of the group).
While I have my own reservations, whatever will happen will be a good chance for you to explore new aspects of roleplay and learn new things. And that is valuable regardless of the result. So…
