"Professions  

Some of our goals with Professions in Warlords of Draenor are to make them more of a personal choice, and less of a mandatory “min/max” selection. To that end, we're removing the direct combat benefits of Professions. Additionally, we've made it easier to level Mining and Herbalism. Healing Potions have gone mostly unused lately, compared to combat stat potions. We chose to solve that problem, along with a problem with Warlock utility, by having Healing Potions and Healthstones share cooldowns. 

Herbalists can now harvest herbs throughout the game world without hard skill requirements. The yield an Herbalist will be able to harvest from each node is now determined by skill level. 

Miners can now harvest mineral nodes in outdoor areas of the game world without hard skill requirements. The yield a Miner will be able to harvest from each node is now determined by skill level. 

Healing Potions no longer share a cooldown with other potions, but instead share a 60-second cooldown with Healthstones. The cooldown will not reset until the player leaves combat."

"Automatically Learned Glyphs 

While leveling, characters unlock Glyph slots at several specific levels. However, in order to get glyphs, characters need to visit an Auction House (and potentially pay way more gold than an average character of that level has yet), or know a Scribe from which to request them. To solve this, we've made characters learn some Glyphs automatically as they level. 

All classes now learn some of their Major Glyphs as they level. Recipes for these Glyphs have been removed. 

At level 25, the following Glyphs are automatically learned by characters of the appropriate class: 

Entangling Roots, Fae Silence, Ferocious Bite, Maul, Omens, Cat Form, Liberation, Pathfinding, Frost Nova, Blink, Fortuitous Spheres, Rapid Rolling, Afterlife, Harsh Words, Flash of Light, Alabaster Shield, Dazing Shield, Avenging Wrath, Templar's Verdict, Levitate, Holy Fire, Fade, Deadly Momentum, Stealth, Flame Shock, Thunder, Healing Storm, Healing Wave, Spiritwalker's Grace, Siphon Life, Drain Life, Demon Training, Ember Tap, Long Charge, Victory Rush, Bloodthirst, Gag Order 

At level 50, the following Glyphs are automatically learned by characters of the appropriate class: 

Might of Ursoc, Nature's Grasp, Rebirth, Rejuvenation, Savagery, Mending, Chimera Shot, Black Ice, Polymorph, Spinning Crane Kick, Denounce, Divine Storm, Word of Glory, Reflective Shield, Smite, Mind Blast, Recuperate, Totemic Recall, Fear, Executor 

At level 60, the following Glyphs are automatically learned by characters of the appropriate class: 

Dark Succor, Unholy Command, Death Grip 

At level 75, the following Glyphs are automatically learned by characters of the appropriate class:
