It is a very good option if you want to avoid doing content with a certain class because you find it hard to play.
It's also a good gateway into crafting for those that aren't sure about it. I almost exclusively leveled my crafters from 1 through 70 with just beast tribes. Gave me basic knowledge, especially since the Ixal require some HQ items to be crafted - unless they did any changes since I did that.
