This is my point, the problem is persisting for a lot of years now, possibly a decade. Sure, when game was all hype and we had 10+ mil subscribers, recruiting was much easier. These days, I have officers burning our from trying to recruit just one or two guys to push us through the last raid tier. I contacted several people who were 4/8 or 5/8, while my guild was progressing on Azshara, some of those guys wanted 8/8 guild to get CE and we had 1 or two saying they would prefer Famed Slayer guild.
Go figure.
It is easy to ask a lot from your players when you are in that sweet spot of up to 500 top guilds. When you get to average spot, the situation becomes dire. And we tried nearly all, from going from 3 days raiding schedule to 2, dropping requirements of gear/experience (even went so far to recruit people with good Heroic logs), not much changed.
