I don't know what is entailed in the process of character revival, but I'd imagine that you'd need your ID and Info...
That being said, if you had to start from scratch, with the changes they have made recently its not as huge an issue as it was even a year ago. You can easily solo 5k/hr with Fields of Valor.
A few weeks ago I took Samurai from lvl 1 to lvl 42 in 3 days. (3 5-6 hr sessions) and I think I only had 2-3 full exp pt's the entire time, one of which I lost more exp then I gained.
With 2 or 3 people you can easily pull in great exp/hr and farm at the same time :P
The game has gotten much more casual for me in that respect, and I'm having more fun now then I've had in ages!
