I'll be trying to get as close as possible to the Storm Disciple I had in Horizons, just switching from martial Arts to a slender twohanded Sword. (...or maybe a Bladestaff, if those are available and not too mainstream.) So I'll need light or no Armor, Meleeskills and Naturemagic, like Restoration, Buffs, Snares and such - and definitely Lightningbolts and Thunder. A total Hybrid.
So I'll likely go for Warrior/Wizard, with a highly limited Selection of Spells. ...I guess that would be pretty pure DPS though, but maybe Rogue or Ranger will be Options too, depending on how restrictive the Classes will be.
