I must be one of the few who doesn't mind the duty finder wait times. I know that they're part of the game as a primary DPS player. I just use the wait time (which is anywhere from 3 minutes to an hour) to work on other things, like crafting and gathering, hunting logs, Atma farming on my main class, etc. You have plenty of time when the queue pops to change back to whatever role you're signed up for. Sure, you have to go without your chocobo for a while, but that's not really that devestating.
