Purchased a couple of jumping potions to get up to speed. A ton of EXP Lvl 50 and below quests have my Samurai nearing Lvl 51 and the SB sidequests got me to WHM 61. Only class I've yet to unlock is Scholar. But I'm now hunting monsters I've never hunter before and done quests that I have never done. It's great to now make the other quests effectively monster slaying practice for the SB content.
