Three new dungeon gear sets found in the latest beta build

The newest WoW: Forever beta build contains three new gear sets, and judging by their names they all come from dungeons: the Defias Enforcer's Garb (the Deadmines), the Violet Sorcerer's Vestments (the City of Dalaran) and the Krol'dok Battlegear (Krol'dok Stronghold, a level 40 dungeon that is not on the beta yet). The Deadmines and Dalaran can already be played, so more details will probably surface soon.

Defias Enforcer's Garb

For melee damage dealers who like a sword.

2 pieces: +10 Fire Resistance
3 pieces: +15 Stamina
4 pieces: +1 Swords skill
5 pieces, Defias Juggernaut: melee attacks can give you 2% more critical strike chance for 20 seconds. Twice as strong in swamps.

Violet Sorcerer's Vestments

For casters, straight from Dalaran.

2 pieces: +5 Arcane Resistance
3 pieces: +10 Spirit
4 pieces, Violet Meditation: your damage spells can let 15% of your mana regeneration continue while casting for 15 seconds. The regeneration is doubled in strongholds and cities.
5 pieces, Summon Arcane Elemental: your damage spells can summon an Arcane Elemental that fights alongside you.

Krol'dok Battlegear

For tanks.

2 pieces: +100 Armor
3 pieces: +5 Defense
4 pieces, Krol'dok Resolve: blocking can heal you for 14 to 23 health. Doubled in strongholds and cities.
5 pieces, Ogre Dominance: taking damage has a high chance to give you +1 Stamina for 30 seconds, stacking up to 20 times.

What this means for Legends of Azeroth

Funny detail: several bonuses get stronger in a certain place, like swamps, strongholds or cities. Leveling gear with a bit of character. Which set will you farm first?
