The very nature of citing a spreadsheet with a proc rate infers you are incorrect. It is random, and that's how it was designed to be. The chance of getting an extra is 20%. Which means that over a long period or large data sample it should even out to be 1 in 5 procs the bonus transmute. Essentially, as an extreme example, you could go 4 months without a single proc and then get a proc every day for a month, which would then average out to be 20%. If it were not random you could guarantee every 5th transmute would proc.
Ya know. It's not the best source of gold, but it's all new gold: Run old raids and vendor all of the gear. In about an hour you can do Highmaul on LFR, Normal, Heroic, and Mythic and get about 6000g total. Some of the other raids aren't quite as fast, but generate similar amounts of gold. You can get some fun new (old?) transmog too if you haven't done much of it.
But every new character made that wants to craft old expansion stuff will have to level using expansion specific materials. Stocking up on profession materials that are already high in demand can be a great idea. This will primarily be materials used to craft the various mounts. Ghost Iron, Trillium, Living Steel, Pyrium etc. are all great candidates to stock up on.
When you launch the game you can choose from two opposite factions (Alliance and Horde), 7 different races for each factions and 6 different classes with very wide mixture of the character's appearance. World of Warcraft play involves the completion of quests while traveling through the story line, gaining experience from the quests to level up the characters and picking up the useful loot to trade with other players. Once a player feel strong enough, or simply just wishes to find some better items, players can visit dungeons where a group can fight together to get better loot from stronger monsters. Near end-game the biggest dungeons require a raid with up to forty players to face and accomplish the hardest challenges for the most valuable items. Another big part of the game is the Player vs Player (PvP) fights where gamers can play againts each other in 2vs2, 3vs3 arenas or battlegrounds for PvP rewards.
"Since [patch] 7.3.5 we’re happy with the overall pace of leveling, he said. "If you’ve chosen to start a brand new character right at the end of an expansion, getting a character fully leveled up and geared up to complete endgame content before the expansion ends, there’s always going to be some time pressure there. That’s just part of the nature of choosing to do that at that stage in time."
