I main heals but used to play SUM (3.0) for maps and expert and really enjoyed its depth. I just returned and find it has been revamped. At first glance it looks streamlined from 3.0 but the guides I see online look just as complex as ever.

For someone who has limited play time and wants to play SUM efficiently what openers would you recommend and why? What are your favorite rotations and why?

Or point me towards a guide that has a great basic primer on the class changes (that doesn't read like hieroglyphics). I would love to see a battle class guide as detailed as Caimie Tsukino's Crafting Guide and equally as human. She managed to unearth the intricacies of a deep deep crafting game in a very efficient way while also making it easy (and fun) to understand. I would love to see this level of attention given to a battle class guide!. If you know one post it here!
