So what if they added a passive for ret where crits from certain abilities give a short extension to the remaining time on inquisition? Basically, if you had x time remaining on inq, then crit with an ability that grants y seconds, you would now have x+y time remaining up to a cap of 33s (the most it can currently go up to through the sub 3 second refresh mechanic.)
This would make crit a more attractive and interesting stat, plus it would give us a little more variation in the rotation. (as it stands now, unless you are using DP, you pretty much always know when you can expect to refresh inq, with this change, you would need to be more actively aware of your time to see if you could sqeeze in an extra tv or not.) plus, it could be balanced based on several variables such as which abilities can activate it and how much of a time extension they grant.
Not sure how much this would affect balance/stat priorities, but I don't think we're so op atm that this would throw everything out of whack. Thoughts?
