Edit: on topic, Blood for Blood is awesome. With Raging Strikes you are on a 20% damage boost most of the time, and with Quelling Strikes you can really wreak some havoc.
I disagree, at least on Ultros. I queue up, do a few dates, or some leves and generally go about my way. Eventually I get in somewhere and get great exp once I'm in. I do this every morning before I get ready for work.
This is actually a great idea for the exp bonus you get from Sanctuaries. Due to the shortage of tanks, I tried take my Gladiator from 15 to 22 (for Provoke) using pure dungeon crawling, and joining parties in progress to save the run whenever possible. However it is a bit exhausting to level that way because of how much attention it demands. Instead I just dungeon until my exp bonus is burned then go do FATEs to relax my mind.
I know many people look down on pure FATE grinding, but to me it is actually pretty fun. Once one pops you jump on your chocobo, the music starts playing, then you rush to the FATE with several other players to beat down on everything in your path. Like some kind of band of raiders (I love Berserk btw). Edited, Sep 29th 2013 2:41pm by fatpolomanjr
