I make use of Low Blow any time I can (or just any time I notice a long cast or recognize a debuff or heavy hit in general regardless of role), so that's no problem, but I wasn't seeing Thrill stacking with convalescence much when I was using it, but I can keep trying.

I'm *very* familiar with people debuffing something to the point a stun or silence immunity comes into play though which is just stupid annoying no matter what role you are cause it interferes with others (reasons I don't abuse shoulder tackle/low blow in parties as a monk or head graze as a machinist)
