I can understand it.
I mean I know it's only fair to stick around and help after getting a pony, but yanno. Most people farm those for hours and hours in total. I can't blame them for being sick of it and wanting to leave. I felt that way about Ifrit >.> Got my pony after maybe two hours, stuck around for an extra 15 or 20 minutes and bailed. Just wasn't fun. Also there are the rare cases where people would have actually had to go regardless and only got lucky with the pony.
How long are you supposed to stay? Another hour? Two?

Kinda reminds me of the bird farms I'm seeing on my server. Lootlocked in order of joining. Completely ridiculous idea and I'm shocked people are falling for it. Who is gonna stick around for two or three drops, realistically, let alone 8? xD
