I would say jumping is a bit a problem extending your movement.

High strength characters reach insane heights by just jumping, making terrain and tactical placement less important. They can basically teleport on a hill or other elevation, when you should in fact be climbing and being affected by difficult terrain. I'm constantly shocked how high and far my 18 Strength characters can reach. Ranges have been shortened and movement rates increased = ranged characters took a double hit. And they're not safe anywhere against high strength jumpers.

High strength monsters like Minotaurs simply fly over obstacles like a 12m diameter Sleet Storm. That's exactly the type of enemy it should be useful against - slow down the scary melee brutes. Nope, they fly over. This might have more to do with a special ability than pure strength though. Whatever it is, there are way too many enemies without wings that just fly wherever they please.
