I've never been able to properly do temple of sacrifice before on account of not really wanting to raid with strangers, and preferring to run group content with friends, so Shadow of Revan's ending was deeply anticlimactic, being thrown straight into a boss without even having a small area to battle through. I've recently learned, you need to be level 80 in order to enter ops now. So is it just impossible to fully experience the ending of the expac without grinding all the way up to cap before finishing it now?
