worth it? depends what you mean. you wont make any money as an engineer. on the contrary, its a huge money sink. im sitting on 10 orbs now, and can do nothing about them. but, its great from a utility perspective. i personally wouldnt give it up.
from a pure min/max perspective, some would take bs/js over eng (the goggles are only a transient advantage, once we are past this tier of gear, they will be obsolete).
