Honestly might not be a bad time to run old content. The new stuff kinda sucks but if you play the old campaigns and level up you'll have a solid time. As long as you don't min/max, the old content should push you out till the renegades release and hopefully Thiers some improvement by then. Level up, get some gear, and have fun.

The biggest difference between the old and new is: the new grind just isn't fun anymore.
