My Warden has one of my armory builds saved with werewolf.

I don't use it often because it's low damage and horrible sustain, but it can be fun for overland pointless content when you're messing around.

For levelling I would always say go with Adept Rider and then either:
Tank: Fortified Brass
DPS/Healer: Order's Wrath

Adept Rider gives Major Gallop and Expedition (people are obviously going to go 'but I get major gallop from pvp line' which would matter if we're talking about once you get to 50 and don't need the Major Expedition anymore but actual damage sets).

For levelling, your damage is not good. You're going to be capable of doing 5-10k dps and so worrying too much about output isn't that necessary when your goal is to get to 50. Moving quicker will help you level quicker no matter if you level in dungeons, questings, dolmens or skyreach/spellscar/blackrose.

As for Alcast, Deltia, HacktheTaurus etc their guides are good - provided you understand the caveat in that they're not designed for you until you go into veteran-grade organised groups where sustain is not an issue, you're chugging 24/7 potions to maintain basic buffs and you actually need harness magicka sometimes. So I wouldn't know the guides, they are fantastic for the content they're designed for - veteran trials in organised groups.

You could use any of the following Mundus Stones:
Thief - standard, default damage. Adds crit rating
Shadow - lesser used option because in organised groups you will hit crit damage cap. Adds crit damage.
Steed - move quicker while levelling, not really for level 50 content. Adds 10% move and health recovery.
Serpent - Woofers struggle on sustain, having to heavy attack isn't great for damage. Adds stamina recovery.

Any of those options will work just fine, depends on your view of things. If you don't know, pick Thief so you dont have to listen to everybody argue that 'thief is best'.
