I haven’t started running my campaign yet, but hope to in a few weeks. I’ve considered this a bit myself, but without any actual play experience…

My thoughts are that the consequences of pushing others around like this will come down the road; sure, you get what you want from them at that point, but if it isn’t an actual win-win situation OR if you do it by breaking people down they will hold a grudge, and these will keep stacking up… and even though you may convince them, others are sure to sow doubt about this, maybe others just as skilled at Manipulation as you?
