The hit boxes thing has always been around with the longer pole arms, at least I think. maybe the slow speed is effecting your judgement of where you're supposed to aim your invisible hit box, I tried cav out after the heavy lance nerf and I still sucked, no worse than I did before though. just can't wrap my head around lancing :c lol
Since every cav and their moms and their mom's mom is still using this beast I don't think there's a problem or else more people would have put it away for a better lance.
example of why I think that, after the 2h stab nerf errybody dropped the German Greatsword for a Danish (or they dropped 2h entirely and went pol(olololololol)e arms), if the heavy lance had got a nerf in comparison to that then we would hardly see the heavy lance anymore, but as it is, every cav uses it still so I don't think it lost that much lovin ;)
Just my dumb ass opinion.
