I am exclusively a PvE player, and I play primarily for questing, achievements, and exploration. Since I'm getting a ton of quest XP, I decided to not let it go to waste and have been levelling up other weapon skills and the class skills I didn't use on my way to 50. The loadout below is for questing, exploring, and general survival in Tamriel.
As it stands right now, I've levelled up all the weapons skills except Restoration to 50. Restoration is coming along nicely. I've also levelled all of my class skills and ultimates, all of the weapons skills (except the final Restoration one), and each of the armor skills to the point where they can be morphed. I've also morphed the mage's guild ultimate, and I've leveled three of my five werewolf skills (as well as the transformation) to the point where it can be morphed. Fighter's Guild is at 9.5 or so.
Generally I play as a Stam DK, alternating between Dual-Wield and Bow. I usually keep a single-target attack, a DOT, either a heal (Green Dragon Blood) or a CC (Shattering Rocks), an "opener" attack (e.g. Snipe or Flying Blade), and an AoE on my bar, in that order. I usually have Pack Leader and Shooting Stars as my Ult's.
For fun sometimes I'll switch to light armor and play at being a mage, but generally the above is my load out.
For the AoE I've been alternating between Eruption and Steel Tornado. I like that Eruption gives me a use for my magicka beyond self heals or crowd control. Considering the options open to me, is there a better AoE that I should try? I don't even have any points in Volley or its morph at the moment because I found it underwhelming.
Also, is there a good DoT or direct-damage attack from my class skills that I might be overlooking because I've been using my weapons skills so much?
