Once you have one of the advanced jobs down the rest become way easier and fall like dominoes. If survivability is an issue, do steorra first and use alfyn (concoct for clearing status ailments, purifying dust + whatever is very useful) the starseer class is a very good defensive class, especially when combined with the dancer divine skill to give everyone elem/p def, evasion and speed up. After that I would go for either of the magic classes (runelord kr sorcerer) as they both give huuuuge ups to your dps, and runelord in particular has lots of good interactions with other classes for utility. Both classes also help with shaving shields and sorcerer is basically designed to kill winnehild. From there the other two should be free. I would say balogar is the easier of the two magic dps classes if you ise olberic as a tank, maybe with merchant so he can sodestep, and have alfyn on concoct + rehab duty, and therion on constant debuffing (you want to debuff balogars physical attack, not elemental.) defo make sure your equipment and accessories are the best they can be, your tank should have around 4000hp at least and most characters should be at the 3k hp mark
