Not really. We've never required more from our applicants than to be interesting in some way. Whether this is experience, gear, progress or personality differs between each applicant, but if you bring neither you're not going to have an easy time finding a guild. Most applications we get now are full one-line answers, ilvl 900 with decent traits but no Mythic experience at all from any expansion. How attractive are you to a Mythic focused raiding guild when you fail to bring anything concrete to the table yet you don't even try to compensate by promoting yourself? (ie "Why should we pick you? - I am good dps and want to raid mythic." is not a great way to convince someone you're actually good).
I mean, this guild and the only other guild-ish (2 guilds that really consisted of 50% the same people) wouldn't even bat an eyelid before declining applications like this in the past. Nowdays we have to consider them not to drop below our magical number of 25 active raiders. Some obviously turn out to be decent, but we also decline around 80-90% of the applications we get.
