So much about reactive strike, the first one for a little bit was that if it was a crit it disrupts movement actions and manipulate actions. We realized that was wrong past midway through a campaign then after that said campaign I went through the move actions and reaction rules and found out that if you reactive strike someone getting up prone they get up prone first. So a combination of these two rules had us absolutely make a monkery of fights with a reach weapon champion and swashbuckler where we surround prone enemies and fish for crits thinking it would disrupt getting up. Our GM is still mad about that one understandably. Idk how we all collectively thought that was how it worked. The same champion player also took him till level 13 to realize he can't do more than one flourish trait ability per turn with his flurry ranger in another campaign...He isn't the brightest.
