Requirements:

Gear: There are no strict requirements beyond an understanding that you will apply your myth tomes first to your main class. As long as you don't split your efforts among classes, you'll be geared in no time.

Research:I expect that you'll have been over the relevant videos/documents with a fine tooth comb. At the least, you should watch, and rewatch, and rewatch, and...
●Mr. Happy's Turn 5 Guide
●BG's World First Win

There are many other Twintania videos out there with lots of lessons to be learned vicariously from them.
For example, can you tell how the white mage died to fireball in the world second win despite having 4.2k max health?

Class Skill:It is important that you know your class well. Of immediate interest with Twintania is that, as a tank or DPS, you are able to maximize your classes damage dealing potential against conflagration. I'm not saying you have to spend some quality time with the training dummy and a parser, but it couldn't hurt...As a healer, it's imperative to be on the ball and have complete command of all resources your class has available to it. For example, prior to this week, I never had much occasion to use Surecast...but Fireball interrupts casting, so it's now more desirable to have that option.

That's all I really ask of people looking to join. Gear up a main, learn the fight like the back of your hand, and aspire to polish your rotations and class usage to be the best ____ possible. If we do this, we can make this community work!
