- charge no longer being an universal ability means that if you have speed advantage over your opponent, you can kite them while attacking - something that was rarely possible in PF1;
- there are far fewer "you lose your full round action so you're bascially screwed now because action economy" effects;
- conversely, any "lose X actions" effects is very important, because it can shut down multi-action abilities, some of which, in particular on monsters, can easily swing the battle around.
Kiting isn't necessarily a good thing to promote. What you are describing sounds like whichever sound has ranged weapons, enough room to maneuver, and equal or higher speed can kite and attack with near impunity until they are out of ammunition. It sounds like a smaller scale battle of Hattin. And actually going and attacking someone with slower speed than moving out of range for melee doesn't even work. Move-attack-move, can be pretty easily countered by move-move-attack. The other two work.
