Knifing Problems!!!

Ok so im getting realllllllllly annoyed in knife matches, im fairly good at them but god dam.. very often i find myself walking right through an enemy, like what the hell! also sometimes ill get stuck inside of an ememy and they can still hit me but i cant hit them oh and speaking of getting stuck i swear to god i get stuck in every map in every game at one point or another. really think you can and should fix the walking through people thing. umm also im not sure if you can fix this problem buut the distance people hit me from is rediculous. its almost as if they have throwing knives. the worst by far is the axe, as soon i see one im like no not fighting them theyll hit me from way too far. While im talking about the axe.. why the hell is the axe left click faster then the knife right click. its the same move exept with a heavier wepeon but its still faster? its about the same speed as the knife left click, yes i know the axe should be alot stronger but in no way faster. they can left click 2ce before i finish my right click with a knife. personally i think that the axe left click should be a tiny bit faster or the same speed as the knife right because one its heavier but also you do have to spin the knife around to stab so that takes time. next is the shovel, the slice is fine but the swing... ohhh my gawwd it would be fine if it always hit you at the same animation point but no, sometimes the hit you 3 seconds after they swing some times theyre not even swinging and sometimes they can swing like 5 times in 3 seconds...i would rant on further but i think ill run out of space
