Just for reference, I'm a 5e player without any PF2 experience. An issue I find in 5e melee combat is that it seems to boil down to static trench warfare, maybe due to the threat of OA. As a thought experiment I was wondering what would happen if we got rid of OA except when given as special ability or feat such as Sentinel. Would it encourage more fluid movement and combat? I posed this question in the 5e forums but one of the responders mentioned that the situation in PF2 is similar to what I'm proposing and I should get opinions from this forum. So what do you guys think? For those who play both 5e and PF2, do you notice any difference in combat with respect to more fluid or dynamic combat in PF2 compared to 5e and is that due to decreased use of OA? Thanks for your insight.
