I personally think those are some strange questions, but I do see the purpose of Guild Apps. One is, like many have said, a laziness check, and on top of that you can tell the motivation a player has based on their response. If its some half-assed thing, they're obviously not serious about raiding, and in most cases just want to be carried.
Asking for a UI is pretty dumb imo. As long as they can perform who cares what they have on their screen, its their account, they're not going to change it up so other people can be comfortable with it. Such a stupid and close minded question.
Our guild has quite a number of questions (16 to be exact), but half of them are short 1 word questions.
1-3 are, your name, age and character/spec.
4-6 are your professions (if you have a gathering profession most people write that they're changing it to a crafting), armory link, and if you're willing to respec to the better spec
7-9, gearing/reforging/gemming strat, WoL link, and if you have Vent
10-12, internet connection type (not sure why we still have this question), our raiding schedule and if you can make said times, and previous raiding experience (ie: saying 5/8 H DS, 8/16H MSV..ect)
13-16, Previous guilds and reason you left (mainly applies to people on our server), how did you hear about us, why do you want to join us and why do we want you in our guild
I don't know about you guys, but i'm sure anyone with half a decent brain could fill that out in less than 10 minutes. Anyone can say: "Hey I want to raid".
Guild apps are a way to see if someone is willing and knowledgeable about their class. If you don't want to fill an app out, then don't.
