For those who have just reached 50, make sure you get with the others to get on the path of getting yourself geared for the endgame content. Also check out the guides posted on some of the first bosses you'll encounter here on the forums.

Also we are still looking for more endgame group content and raids, if you find anyone refer them over, we could use at least 1 more of each for now, especially those that are already level 50.

Thanks.

Here is a good guide for where to go and what you need to do at 50.
