You can also do crafting to get beta tokens, If you don't have any trade skills you can just beta buff a toon then go to the crafthalls and do an easy TS quest over and over. You will have to buy the materials but you start with 75k as a betabuff. My personal favorite is the Jewel crafting 12 this year. It's simple, make a round cut, trillion cut and square cut energized gemstone. You can probably find an easy combine whatever TS Is your favorite though. I just went through the JC list looking at what was required for completion and that was the simplest one. You get 1 token per task completed. Making 3 cut gems takes around 10 seconds if you get the recepie down, and add it to the favorite list. make sure to buy Jewel crafting mastery and put on your JC trophy, makes learning the recepie easier when you're just getting it started. buy 3 cutting tools and make them into the square, trillion and round respectively by combining the tool in the bag by itself it will change. I busted out my tokens in under 30 mins just like last year. They sell all the stuff you need for basically nothing in the craft halls and even supply the raw materials like the energized gemstones, jewelers glass pre made, and planar jewelers kit.
Sorry it's sorta long but I put some extra stuff in to explain things to those who don't do TSing or JC. I'm not exactly sure we need 100 tokens but it can't hurt right? I was told the magic number is 50. I always go over though, last year I did 120 per account. Thanks for your tip though, I didn't know there was any other way to get tokens besides helping a GM test something, kill or craft.
