Hi tony, just wanting to say that yeah you can definitely fill spots with openraiders. I'm in the US but I was the lead for my guild group for heralds and we always had about 3x as many non guildies sign up on openraid as we actually needed. People were so desperate they would make alts on my server to whisper me if I turned them down. If I had it to do over again I would not have bothered with the guild group and the endless hand holding that entailed.
