Lightforged draenei (7.3.5) - "For untold millennia, the Army of the Light waged war against the Burning Legion throughout the Twisting Nether. The draenei most committed to their long crusade would undergo a ritual to become Lightforged, infusing their bodies with the very essence of the Holy Light. After finally achieving victory on Argus, the Lightforged Draenei have undertaken a new mission: protecting Azeroth from rising threats and helping the Alliance push back against Horde aggression."
Jewelcrafting is a crafting profession that revolves around gems. You prospect various ores turning them into gems and cut the gems. The cut gems can be added to socketed items. In addition you can craft rings that can either be disenchanted or sold as gear. The BfA gems sell well, particularly the haste gem and the Epic Kraken’s eyes. Due to price and gem yield ratios in BfA you should only ever prospect platinum ore. The jewelcrafting panther mounts are the best old world recipes, and these mounts are great for gold making!
Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.
PLUNDER THE ISLANDS OF THE GREAT SEA – Explore Azeroth’s uncharted isles in Island Expeditions. Battle in groups of three as you race against cunning rival intruders (or enemy players) to collect the island’s resources and fuel the war effort.

In addition to questing and running dungeons in the Broken Isles, players should also remember to visit their class hall, which is like the garrisons from Draenor, but themed around your character’s class.The quest lines in your hall provide valuable experience and open up important features, like artifact weapon upgrades, that will drastically up your character’s power.
