We're also playing with humans though, so dismissing human reaction as having no place here or being exaggerated, when folk are new or not expecting that kind of interaction, is just unrealistic. Could people do better? Sure. But the point is, let's not just assume the worst of people. Most of us get better over time.
I would consider, also, not dropping on top of another group fully warded, when they are not, if you want to increase your chances of RP. Yeah, I get that makes you more exposed, but it will also likely reduce the knee-jerk reaction factor, because it looks less like you're just hunting for a fight that you only intend to win from your set up.
There's plenty of conflict opportunities on this server that don't involve trying to get a foot-up on your RP opponent mechanically. If you try to mechanically outplay your opponent in advance, they probably will run away. That won't change. Perhaps it's a better solution to approach them differently.
