I meant, leave the current harnessed shadows as is. But bring back the harnessed shadows with heals as another tier which you can put points into,if you use it you cannot use the DR harnessed shadows.
as for the 2nd idea , it doesn't have to be 10% it could 5% or whatever, but it would off the crit damage, ok good point on the balance spec then if you use Force tech then it cancels the passive..
