Hmm, I can only answer the Flesh Giant question 
Assuming I'm "recruiting" a Warcraft player, I would want to know:
1. Their values: Are they one of those rude Wow players that ganks lowbies, and spams trade chat with profanities or Chuck Norris jokes? Do they use in-game cheats? Are they a ninja? Will they be a good fit for the guild culture (progression vs casual), etc?
2. Their aptitude: Even if they are undergeared, Would they be willing to learn new boss fights and do they have the raw skill that will make them great players once they get great gear. Do they listen or is it clear that they won't improve as players?
3. Their experience: What class, level, spec they are, what guilds they've been in and if they left, why did they leave?
