Eos/Dm always had their own requirements even before guild rankings were introduced
Keeping requirements doesnt make them pro or anythin..and lvl requirements r there because u wudnt like a low lvl player random inviting u askin u help in low lvl maps or asking u for gold/equipments or even worse is pming the gm to promote him ..i wont say high lvl ppl don do that..But it is very mch minimised..and if u say so..other guilds who dont care for ranks doesnt recruit any random player walking in town..as far as i know getting in those guilds..u need a recruiter who knows u well n can vouch u and if not u shud be a good player who could be trusted. And one last thing u should really check out our guild chat
