Claim Your Just Rewards!
There are vendors waiting in Dalaran, Shattrath, Orgrimmar and Ironforge that will exchange your hard-earned Timewarped Badges for wondrous rewards, such as mounts, transmogs, commendations that increase your reputations with Burning Crusade, Northrend and Cataclysm factions. Picking the event-only quest "A Shattered Path Through Time" in your Garrison will grant you a Seal of Inevitable Fate along with an Iron Fleet reasure Chest once you complete five Timewalking dungeons.
The Perks of Timewalking
What's in for me if I devote time to timewalking you may ask. A lot! Timewalking has become the most efficient way of gearing up characters when reaching Level 100 in the shortest time possible. At Level 100 the gear drops are of item level 660 (675 warforged). As mentioned above another reward is the Iron Fleet Treasure Chest, 1 bonus roll seal and 500 Valor. There's also this Infinite Timereaver mount that drops from any Timewalking dungeon.
I'm Geared Your Argument Is Invalid!
...let me finish! There are VARIOUS rewards waiting to be exchanged for your tokens! The toys you can earn include Gurboggle's Gleaming Bauble, Tosselwrench's Mega-Accurate Simulation Viewfinder,reputation commendations are available for Therazane, Earthen Ring, Ramkahen, Guardians of Hyjal, Wildhammer Clan, Dragonmaw Clan and other items include various Heirlooms that upgrade your existing heirloom slots to grow in power, such as Ancient Heirloom Scabbard.
Quickly Badge Farming
1. From the first dungeon you complete, you get 500 Badges (may not occur more than once per event).
2. There's a Call-to-Arms bonus which grants 50 Badges.
3. Completing a dungeon gifts 10 Badges.
4. A Normal boss kill grants 5 Badges (End Boss kill grants 10 Badges).
A great thing to know is that some outdated items are even better than items of a higher item level, let me explain! Legendary effects do work with Timewalking and they are awesome. You can totally destroy them damage numbers in Recount (or Skada?) that's why it'sthe ideal time to dust off your good old legendary cloak from Mists of Pandaria should you by any chance own one.
Gem Slots - the more the better!
Gem slots don't scale down, that's why the slot count is important and may boost your dps by a lot. That's why you should favor for example Bracers of Destructive Strength as they have two slots which can be filled with epic gems, giving you up to +20 Strength.
Don't use %-based trinkets
If you want to use trinkets giving XP bonus, it's normally a bad idea. Trinket class drops that increase damage dealt by a flat percentage immensely decrease in power when scaled down rendering it to nothingness.
