I also tried to main a Bishop and if you have lots of time to wander around ingame looking/organizing a party it can be less painful, but if you looking for some casual play don't do it because you'll end up rerolling because no one will take you to exp and you will logout without doing nothing.
Of course everyone wants a 70+ Bishop, but getting there is the hard part. If you play with some friends since the beginning to help you go for it, you'll enjoy a lot.
